What is the Fluke 1537 Advanced Insulation Tester?
The Fluke 1537 Advanced Insulation Tester is a high-performance insulation resistance tester designed for UK electricians and electrical maintenance technicians who need fast, stable and accurate insulation testing on industrial, commercial and solar installations. With adjustable test voltages from 250 V to 2500 V and insulation resistance measurement up to 500 GΩ, it supports everything from routine commissioning to advanced fault diagnostics. Built for demanding environments, the Fluke 1537 combines powerful insulation testing with AC/DC voltage and resistance measurement in one compact instrument. Intelligent functions such as automatic PI DAR and DD calculations remove guesswork and help technicians quickly assess insulation condition with confidence.
How does the Fluke 1537 stand out in everyday use?
The Fluke 1537 is designed to save time on site. Fine-tunable test voltages in 100 V steps, a short-circuit current up to 5 mA for faster stabilisation, and advanced test modes like Ramp Testing make it easier to detect insulation degradation before it becomes a failure. Built-in memory and USB connectivity allow results to be stored and downloaded for reporting and compliance.
