Product Details

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, capable of measuring AC and DC stray voltage and stray current respectively, no power supply needed, safe and reliable. It is suitable for testing the current and voltage generated by steel rails, water pipes, cables, etc. in coal mines, preventing premature detonation and other explosion accidents caused by stray current discharge, and reducing the fire source in the mine to the lowest limit.
