Introduction to the product of [pressure tester]

The 125B type voltage tester is an instrument for measuring the compressive strength. The test voltage and leakage current are displayed by LCD, the high-speed MCU of Atmel company is used for control, the alarm value of leakage current is set by pressing the key, the test time, 100mA and other parameters are set, and the software debugging method is used to calibrate, which makes the debugging simple and convenient. It has the function of power-off memory parameters. The working state is clear at a glance, simple key operation, will learn. This instrument is not only suitable for rapid flow test of production line, but also suitable for multi-function and high precision requirement of laboratory.

The design principle of the instrument accords with the safety performance testing requirements of , , and other national standards. It can be used to test the electrical strength of the apparatus which adopts basic insulation, additional insulation and reinforced insulation. This instrument is suitable for all kinds of household appliances, power supplies, cables, transformers, terminals, switches, power plug holders, power tools, electronic instruments and other safe voltage and leakage testing.
