The ACT/223 Advanced Insulation Tester streamlines installation and maintenance by combining versatile measurement functions into one powerful tool.

The ACT/223 features five insulation test voltages up to 1000V, measuring insulation resistance up to 20 GΩ. It includes a 200 mA low-ohms earth-bond continuity test, alongside Polarisation Index (PI) and Dielectric Absorption Ratio (DAR) measurements to accurately assess insulation quality and its stability over time.

Built for the demanding conditions of UK fire alarm industry, the rugged ACT/223 comes complete with a protective rubber holster to help withstand accidental drops on-site. Its large, backlit LCD screen ensures crystal-clear readability inside dark ceiling voids or poorly lit rooms. An automatic 10-minute power-off feature prevents unexpected battery drain. Every unit comes fully equipped with a durable nylon carrying case, a premium test lead set with detatchable crock clips, and 4x Alkaline AA batteries ready for immediate deployment.

Additional functions include AC/DC voltage measurement up to 600V, resistance measurement up to 600kΩ, and a continuity test with audible buzzer.
