High-Voltage Insulation Resistance Tester (Up to 10TΩ)

This advanced insulation resistance tester is designed for high-accuracy insulation diagnostics across a wide voltage range from 250V to 5000V. It delivers powerful performance with a maximum insulation resistance of 10TΩ and short-circuit current up to 5mA, making it ideal for professional electrical and industrial testing applications.

Equipped with diagnostic insulation test modes such as IR, PI, DAR, DD, SV, and RAMP, this instrument ensures comprehensive evaluation of insulation quality. The built-in Bluetooth communication feature allows real-time data transfer and monitoring on PC or Android devices, while memory and logging functions enable easy data management and analysis.

The tester also includes a filter function to reduce noise interference and ensure stable readings. Its rugged IP65-rated design (with lid closed) and rechargeable 12V battery make it reliable and portable for field use.
