Description
The MRT pro is a high-end, microprocessor-controlled 10kV programmable insulation resistance tester designed for precision diagnostic insulation testing on critical high-voltage assets. It features 50V–10kV continuously adjustable test voltage (10V step), measures up to 20TΩ, and integrates IR, DAR, PI, DD, SV full diagnostic modes with real-time V/I/R/temp curves。
Equipped with a 5-inch true-color touchscreen + rotary knob (triple control: touch/key/knob), Bluetooth 5.0 + USB 2.0, 14.8V Li-ion battery (12hrs runtime), and CAT IV 600V safety rating, it delivers laboratory-grade accuracy and industrial-grade durability in harsh EMI environments. Ideal for transformers, generators, HV cables, motors, switchgear, and bushings in power utilities, industrial plants, and service teams.
