Why Choose InsulTeste
Professional High-Voltage Diagnostics
The InsulTeste Pro is a robust 2500V insulation resistance tester designed specifically for UK electricians and industrial technicians. Whether you are conducting a motor winding inspection or performing routine transformer maintenance, this digital megger meter delivers accurate, repeatable results. With easily selectable test voltages of 250V, 500V, 1000V, and 2500V, you can safely test a wide variety of assets without needing multiple instruments.
Comprehensive 200GΩ Measurement Range
Go well beyond the limitations of a standard multimeter. Our auto range megohmmeter measures insulation resistance from 1MΩ right up to an impressive 200GΩ, making it the perfect cable megger tester and switchgear testing tool for deep fault finding. The large 2000-count backlit LCD ensures you can easily read critical measurements in dimly lit switch rooms, basements, or industrial workshops.
Built-in Safety and Data Storage
Safety is paramount in high voltage resistance testing. This AC DC voltage insulation tester allows you to verify live circuits (10V to 600V) before initiating an insulation test, protecting both you and the meter. Furthermore, the 100 data storage megohmmeter functionality allows maintenance teams to record and recall test results on the fly, dramatically streamlining your preventive maintenance reporting and compliance documentation.

Customer Reviews
Brilliant piece of kit for the price. I use this 2500V insulation resistance tester for testing 3-phase motors in our factory. The 200G ohm range gives me a much clearer picture of winding degradation than our old analogue megger.
Ordered on Tuesday, arrived Wednesday morning. The auto-ranging feature on this digital megger meter saves so much time when doing cable insulation testing across large commercial sites. Very robust build.
As a high voltage contractor, I need dependable gear. The built-in 600V AC/DC voltage verification is a lifesaver for checking dead circuits before hitting the 2500V test button. Highly recommended.
Great electrical insulation resistance meter overall. The 100 data storage feature is very handy for writing up my maintenance reports. Only dropping a star because it takes 8 AA batteries, making it slightly heavy, but it does mean it lasts ages.
I was comparing this to a much more expensive Fluke model. For switchgear testing and general industrial repair, this unit performs flawlessly. The backlit LCD is super bright for dark plant rooms.
Very capable transformer maintenance tool. The 250V to 2500V output options mean I can use it on sensitive low-voltage stuff and heavy industrial gear. The carry case is a bit snug with all the leads, but the meter itself is top notch.
Excellent value for money. Upgraded to this 200G ohm insulation tester for our facilities management team. It's incredibly straightforward to use and the automatic discharge feature gives great peace of mind.
