FZY-3 Stray Current Tester is a portable rectifier instrument with high sensitivity and multi-range protection circuit. Its characteristics are: wide measurement range, with a total of twenty ranges, able to measure AC and DC stray voltage and stray current respectively, no need for power supply itself, safe and reliable. It is suitable for testing the current and voltage generated by steel rails, water pipes, cables, etc. in coal mines, preventing early explosion and other combustion and explosion accidents caused by stray current discharge, reducing the fire source in the mine to the lowest limit.
