Digital Insulation Resistance Meter, AP-6688B, Ground Resistance Meter, 1999 Count, 5000V Voltage Measurement, 200G Ohm Insulation Resistance Meter, f

Wide Test Range: ✔ Depending on the model, the output test voltage can be selected from 500V, 1000V, 2500V, or 5000V. The insulation resistance measurement range reaches up to 200GΩ, and it can measure AC voltages (up to 750V).

Easy to Use: 🔒 Press the data hold key or activate the backlight during testing to easily read the values. It also comes with a stand on the back, eliminating the need to constantly hold the instrument, saving you time and effort.

Safe Design: 🧱 The shock-resistant cover and dust- and moisture-proof construction make it ideal for outdoor work environments. Furthermore, the insulation resistance tester's design complies with IEC-1010 double insulation, environmental pollution degree 2, and overvoltage category II safety standards promulgated by the International Electrotechnical Commission.

Features: 🔋 Low-power CMOS dual-integral A/D conversion integrated circuit, automatic zero calibration, automatic polarity indication, and overrange indication. Suitable for measuring the insulation resistance of switches, cables, and other electrical equipment and insulating materials. 【Warranty】We offer a 12-month warranty.
