COMMON   GROUND   POINT        Z111

As per ANSI/ESD S20:20 all conductors including Personnel must be electrically connected and attached to a known ground.

A common question about anti-static wrist straps is how and where to ground them. Anti-static work station operators need a convenient method of grounding their wrist straps where the ground cord won’t get in the way of their work. This convenient device  provides the means to ground anti-static wrist straps at your work station.

The strong bracket mounts (with just 2 screws) to the bottom front edge of your work table or bench. Two banana sockets located in the front of the bracket allow for easy connection of two wrist strap cords (for operators working side by side).

Features

  • Designed to mount under bench, saving work surface space
  • banana jacks allow for grounding two anti-static wrist straps at once
  • Lug for attachment to earth ground
  • Front edge bench mounting of ground block via two screw slots

ELECTROSTATIC   ALARM - Z201

The  Electrostatic Alarm Z201 is a portable, battery-operated instrument, incorporating the latest technology, to indicate the presence of approaching static electricity. It is designed to provide a quick and convenient method of locating static charges and their approximate charge levels. It is primarily intended for use in static-safe handling areas, as an early warning system to alert the personnel nearby.

The hazard may be in the form of personnel who are generating static or personnel who may be holding a charged object without observing the standard safety procedures for handling static sensitive devices.
 
The instrument incorporates a unique self-resetting feature and therefore requires no manual adjustments or zeroing. It can be kept 'ON' for continuous monitoring of critical static-safe areas, thanks to its remarkably low current drain of only 1 ma.

THEORY OF OPERATION
A static charge on any object produces an electric field whose strength is an inverse function of the distance from the charge. A given magnitude of charge always produces a given field strength at a given distance.

The unique sensor of the instrument actually responds to this electric field. However, more specifically, it senses only changes in the electric field, so to detect a charge there should be relative motion between the instrument and the charged body.

ESD Safe Smoke Absorber

Soldering smoke contains salicyclic acid, pinene and other noxious chemicals which are harmful to health when inhaled. Collophonium which is the residual part of distillate from tree resin has an irritating effect on the human respiratory system and so have other inorganic derivatives (chlorides). This causes nausia and headaches.  The long term effects can be more severe.  The gases released from the flux during soldering also severely irritate the eyes and often lead to eye diseases.  Soldering fumes are now recognised as a serious health hazard in the electronic industry.

The model 493 is a compact, portable, self-standing, low noise unit which can be adjusted to any angle for maximum smoke absorption and is specially designed to suck the harmful fumes away from the operator which then gets absorbed onto an activated carbon filter.

    



HUMAN  BODY  VOLTAGE  CHECKER    Z2055 & Z2055A 

This instrument is designed to measure the Static Voltages carried on a human body.  It is a good auditing tool to verify whether Personnel entering an ESD safe area are carrying any hazardous charges on themselves. It can also serve to verify whether all the ESD protection measures which have been taken to make a particular area ESD safe are effective. By such measures we mean conductive flooring,  antistatic table mats, wrist straps, static sheilding bags, ionizing equipment, conductive containers and bins etc.

It is very simple to use and only requires the personnel under test to touch the Button on the instrument and directly read the charge level in volts on the meter.

The Z2055A version gives a hazard warning if Voltage measured exceeds 100V

bar type static eliminator line


STATIC ELIMINATOR - BAR TYPE SHOCKLESS Z2075

Introduction
The generation and accumulation of unwanted electrostatic charges, both surface and airborne, poses a serious problem in various industries and processes.  For example, static charges can lead to sticking and crumpling of polyester films while being processed on the machines. Collection of dust and other particulate contaminants on surfaces due to static is another example. The discharge bars and the power supply are used primarily in cases where disruptive static charges on fast moving material webs impair production processes and need to be eliminated.

How it works
This static eliminator works on the principle of high voltage corona discharge, to produce the neutralising ions. This Static eliminator system is designed to neutralize the charges by the “Ion showering” process wherein the surface charges present are neutralised. It is designed for continuous use and the unique “Shockless bars” ensure total safety even if the electrodes are accidently touched.

Application areas
Plastic film and paper industries, Glass related industries
Textile Industries, Pharmaceutical industry, Clean rooms.

Note: Not to be used near flammable gases, vapours or materials.

STATIC  CHARGE  METER (DIGITAL) Z205

The Static Charge Meter Z205 is a non-contact, light weight digital instrument designed to measure static voltages on objects & surfaces. It features a large LCD display to indicate the magnitude and polarity of the electrostatic charge directly in Kilovolts.

The special circuitry enables repeated and drift-free measurements without continual re-zeroing. The instrument has good directional sensitivity and is ideal for measuring electric charges encountered in critical electronic assembly and storage areas as well as Antistatic Work Stations. It can also be used for Plastics, Paper, Textiles, Food, explosives and Pharmaceutical Industries.

The unit gives direct readings of electrostatic potentials on any surface, when held at a distance of 5 cms. However, higher electrostatic potentials can be measured by proportionately increasing the distance from the meter to the charged object.

The use of very low current circuitry results in a long battery life of over 6 months under normal use.

OVERHEAD  STATIC  ELIMINATOR  (IONIZER) Z209

The generation and accumulation of unwanted electrostatic charges, both surface and airborne, poses a serious problem in various industries, work areas & laboratories. For instance, static charges can cause havoc in the electronic assembly shopfloor.

This OVERHEAD unit can be conveniently hung over the work area for a large coverage to neutralise the charges on personnel or on any item entering an ESD sensitive area. This is achieved with a stream of ionized air. "Ion showering" is the only effective method of removing static charges from non-conductive objects and surfaces.

The unique high-efficiency pulse circuitry provides fast discharge with limited air flow.  It works on the principle of high-voltage corona discharge to produce the neutralising ions.

Ion Balance is maintained irrespective of supply voltage and even if the discharge electrodes are dirty. Balanced output is essential when used in critical ESD sensitive areas.

STATIC  ELIMINATOR  (IONIZER) Z207

The generation and accumulation of unwanted electrostatic charges, both surface and airborne, poses a serious problem in various industries and laboratories. For instance, static charges can create havoc with sensitive equipment and electronic components.

This Bench Top instrument is designed to neutralise your ESD work-station or ESD protected area with a stream of ionized air. It does what Wrist straps and Conductive mats cannot do - i.e. remove static charges from non-conductive objects and surfaces.

It is able to rapidly neutralise potentially dangerous charges in a localised area.  An axial fan gives the desired air flow to neutralise static on specific objects rapidly, as well as control static in the general area in front of the ionizer.

This is a powerful, trouble free and compact solution to static control problems anywhere. The unique high efficiency ionization pulse circuitry provides fast discharge with minimum air flow. A high air flow would lead to operator discomfort and may also disturb small components.

This static eliminator works on the principle of high voltage corona discharge to produce the neutralising ions. It is designed for continuous use and a current limitor circuit ensures operator safety even if the ion emitters are accidentally touched.

The Z207 has special circuitry to ensure a balanced ion output. This ensures that no net charge is induced by the ion shower. Balance is maintained irrespective of supply voltage and even if the discharge electrodes are dirty. Balanced output is essential when used in ESD protected areas.

CONTINUOUS WORKSTATION MONITOR Z107

The Model Z107 has independant circuitry designed to continuously monitor the connections to earth of the Wrist Strap and Work Surface.

WRIST STRAP
This section continuously monitors the wriststrap to detect loss of continuity between operator and monitor.  Conditions such as broken coil cords and improper contact with the skin are detected instantly to alert the operator before serious and expensive ESD damage can occur. As there is no resistive return path from the wriststrap, it uses the 'Capacitive AC principle' to check if the operator is adequately grounded. The Wrist Strap section is automatically activated when it is plugged in. Continuous monitoring reduces the need for periodic checks and audits and also ensures greater security.

WORK SURFACE (MAT)
The work surface is monitored by a DC Resistive loop  and a warning is given in case the Surface-to-Ground resistance exceeds the safe threshold value of 10 megohms.

RESISTANCE - TO - GROUND  MONITOR  Z109

The grounding of ESD protective equipment is used to reduce the chance of damage to susceptible parts and assemblies resulting from ESD.  The first step in ensuring that everything is at the same  electrical potential is to ground all components to the same electrical ground point. This point is called the common point ground and is defined by ANSI EOS/ESD/S6.1 as a system or method for connecting two or more grounding conductors to the same electrical potential.

ANSI S6.1: Highly conductive work surfaces and ESD protective flooring should be connected directly to ground eliminating the resistor. For static dissipative work surfaces and ESD protective floor mats the resistors are optional.

The Model Z109 verifies that the bonding-to-ground of the ESD workstation is less 5 ohms. This unit continuously monitors and reports the integrity of point-to-ground connections on ESD workstations and other associated items. The 5 ohm threshold has been selected to accommodate long interconnecting cords used for Grounding.

Transcranial Direct Current Stimulator  Z905

Transcranial Direct Current Stimulation (tDCS) is a brain stimulation technique that has been available for several decades; the procedure was earlier described as brain polarization. As presently practised, it involves the delivery of a very small direct current (about 1-3 mA) for a brief period (about 20 min) through appropriately-sized electrodes, one or both of which are placed upon the scalp.

Although tDCS has not been formally approved for any clinical indication, it has been experimentally used with some success in a variety of neuropsychiatric disorders ranging from depression to refractory auditory hallucinations in schizophrenia.  tDCS is very well tolerated.

The last decade has witnessed an explosion of research in the field, with nearly a thousand hits emerging from PubMed, alone.
