Surface resistance test kit – the one that I am looking for
There is always a need to have efficient and good static control equipments in any static electricity and Electrostatic Discharge (ESD) control program.
The most basic static control or ESD equipment is the surface resistance test kit.
This surface resistance meter measures surface to ground resistance or RTG for most of the static control products used within any ESD protected area (EPA) such as anti-static work surface mats, ESD carts, ESD smocks, ESD shoes, ESD flooring and ESD chairs.
There are two types of surface resistance meter available in the market place: the analogue and the digital type. For the digital type of surface resistance meter, the end user reads the measured resistance on the meter after testing is done. For the analogue type, the user is required to know how to read the meter in order to know the measured resistance value.
The digital type of surface resistance meter is definitely friendlier user then.
A typical surface resistance test kit consists of two five pound electrodes, two electrical test leads and a meter. For some test kits, two parallel probes are placed on the bottom of the meter to allow the surface resistivity measurement.
Most of the surface resistance test kits allow measured resistance in the range of 1×10E3 to 1×10E12 ohm at test voltages of 10V or 100V.
A good surface resistance meter would allow any user to measure surface resistance of his static control products with all the required information being given by the meter such as on ambient temperature and relative humidity of the testing environment.
However, an efficient surface resistance meter would be the one that allows user to measure the surface resistance very quickly at the set test voltage without the need to know how to read the measurement results on the meter.
One of the most efficient Surface resistance test kit that I had ever used was the Desco model 19775 surface resistance meters. The new models of surface resistance meter in the market are the good meters but they are not the efficient meters as the measured resistance value only appears after the ambient temperature and relative humidity of the environment are displayed. These meters slow down the checking process of the static control products inside the EPA especially when there are numbers of them to be measured periodically.
Where is the anti-static surface resistance test kit that I am looking for?
After many searches around the market, the efficient static control equipment for surface resistance measurement that I need is still within my reach. It is still out there. And that saves me ….. plenty of time.
