Key Features:
The Fluke 1535 and 1537 Insulation Resistance Testers provide fast and reliable insulation testing for industrial, commercial, and solar applications. Fluke designed these high-voltage megohmmeters to help technicians troubleshoot, commission, and maintain electrical systems with confidence.
Both models offer selectable test voltages from 250 V to 2500 V and measure insulation resistance up to 500 GΩ. As a result, users can evaluate everything from low-voltage circuits to large industrial equipment and photovoltaic installations with a single instrument.
Automatic Polarisation Index (PI) and Dielectric Absorption Ratio (DAR) calculations help assess insulation condition while reducing the influence of environmental factors. In addition, the high short-circuit current capability delivers faster and more stable measurements, particularly on larger systems.
The CAT IV 600 V safety rating and built-in live voltage warning enhance user protection during testing. Furthermore, the rugged portable design makes both instruments suitable for demanding field environments.
The Fluke 1537 adds advanced diagnostic and data management capabilities. These include adjustable test voltages in 100 V increments, dielectric discharge (DD) calculations, ramp testing, onboard data storage, USB connectivity, and PC software for reporting and analysis.
Both models feature a large LCD display with analogue-style resistance bar graph, helping users interpret results quickly. Long battery life also supports up to 6,500 measurements at 250 V, improving productivity during extended testing programmes.
For professionals who require high-voltage insulation testing and dependable field performance, the Fluke 1535 and 1537 provide a practical solution for electrical maintenance, troubleshooting, and solar system testing.
