The Electrostatic AlarmZ201is 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.

As per ANSI/ESD S20:20 all conductors including Personnel must be electrically connected and attached to a known ground.
A common question aboutanti-static wrist strapsis how and where to ground them. Anti-static work station operators need a convenient method of grounding their wrist straps where the ground cord wont get in the way of their work.This convenient deviceprovides 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

Wrist straps and ESD footwears are the first line of defence against electrostatic charge build up on the human body. They are designed to carry away this charge as soon as it is generated. At the same time the wrist strap/footwear must remain electrically safe for the user. Thus, it is important to test every wrist strap/footwear regularly.

In order to protect sensitive electronic components, the maximum wrist strap resistance should not be more than 10 meg ohms and footwear resistance should not be more than 35 Mega ohms. On the other hand, the resistance should not be less than 0.75 Mohm as protection to the wearer from dangerous levels of voltage and current flow.

The wrist strap and the footwear tester checks these parameters under actual operating conditions with the strap on the wrist or footwear to the foot. It clearly indicates whether or not the wrist strap/footwear system is safe to use.
ALSO AVAILABLE WITH FOOTWEAR RANGE UPTO 100M OHMS

This instrument is designed to detect the level of Static Charges present on a human body and allow access into an ESD safe area provided the Body Static voltage is under 100V.

It is very simple to use and only requires the personnel to Press & Hold the Test Button on the instrument. If the Body voltage is under 100V, the Green PASS Led will light and the magnetic lock is deactivated for a few seconds thereby allowing access through a door or turnstile.

The personnel should normally be free of Static Voltage provided proper ESD protection measures have been taken. Therefore, it also serves to verify whether the measures taken to make a particular area ESD safe are effective. By such measures we mean conductive flooring, ESD wrist straps & Footwear, ionizing equipment, etc.

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.

ThisOVERHEADunit 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.

This is a wide-range, battery operated, portable instrument for measuring Surface Resistivity of virtually any surface. In the circuit industry, products such as packaging materials, component storage bags and trays, work bench surfaces, table and floor mats, conveyor belts, etc., have resistance values which need to conform to stringent specifications. Moreover, these values are expected to fall within specified limits. The Surface Resistivity meter can play a vital role in monitoring and checking the resistivity characteristic of the above items.

Surface Resistivity, Resistance between 2 points, andSurface to Groundcan all be conveniently measured in accordance with EOS/ESD Association Std S4.1. Measurements in the conductive range i.e. upto 10^5 are made at 10V and all higher values at 100V. Measurements can be taken with built-in parallel electrodes orspecial external probes. A separate cord is also provided forSurface to groundmeasurements whereby the resistivity differential between any surface and any chosen ground can be determined.

TheStatic Charge Meter Z205is a non-contact, light weightdigitalinstrument 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.

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.
