【Static Meter】The electrostatic field tester is a non-contact portable electrostatic field tester, which can measure the surfaces electrostatic value of objects and the ion balance of electrostatic eliminating equipment. 【Accurate Test】Move the meter from far to near to a distance of 5cm from the object being measured (calculate the measurement distance from the groove at the front of the meter) and read the reading of the meter in kV. 【LCD Digital Display】Measurable range is 0~50KV. 5 times/s LCD display renewal rate, easier to observe and record values. 【Clear Function】The zeroing key uses button mode, which is simple and fast, and speeds up the measurement of the measuring device. 【Portable】This electrometer is small in size and light in weight. Ideal for measuring the electrostatic properties of textile materials (fibers, carpets) and other plate materials (paper, rubber, plastic) in laboratory settings.
