Fluke 1535/1537 2500V Insulation Resistance Meter (Digital High-Voltage Megohmmeter)

Key features

Up to 500 GΩ insulation resistance measurement range
Fast-measurement design, faster & stable resistance reading, higher efficiency
Automatic calculation of polarization index (PI) and dielectric absorption ratio (DAR)
Low power design meets the requirements of high-intensity work: up to 1300 times of 2500 V measurement, and up to 6500 times of 250 V measurements*
High-safety design with dangerous voltage alarm function, and complies with CAT IV 600V standard and China power industry specifications DLT845
The new high-reliability design, all specifications are met even under the environment of 50 °C temperature and 80% RH; all probes and corresponding ports are tested for 30,000 mating test

Fluke 1537 adds the following features based-on the above features:

AC/DC voltage and resistance measurement
Short-circuit current >5 mA, faster and more accurate
Fine-tunable test voltage: 250 V to 2500 V,100 V step
Automatic calculation of dielectric discharge rate (DD), find insulation problems that are not easily detectable in multilayer insulation
User-defined label, timing test, measurement results storage
Download data with provided PC software
3 years warranty
