Chauvin Arnoux High Performance Insulation Tester 50 V Min, 1 kV Max, 4 TΩ Resistance, CAT III P01138902

Chauvin Arnoux P01138902 insulation tester is engineered for high-precision electrical insulation diagnostics, supporting test voltages from 50 V to 1 kV and insulation resistance measurements up to 4 teraohms. This CAT III rated instrument meets rigorous CEI 61010-1 + A2 and CEI 61557 standards, making it suitable for demanding industrial, electrical maintenance, and HVAC environments.

The device features a digital LCD screen with backlight and bargraph for intuitive readout of test results. It offers automatic calculation of derived parameters such as dielectric absorption ratio (DAR) and polarization index (PI) to evaluate insulation quality effectively. Programmable test periods and resistance curve plotting (R(t)) provide extended analysis capabilities for site conditions.

Continuity tests ranging from 0.01 Ω to 40 Ω are equipped with audible beep signaling and lead compensation to ensure precise continuity evaluation. Capacitance measurement is conducted automatically between 0.005 and 4.999 μF immediately following insulation testing, enhancing multi-parameter assessment efficiency.

The tester is powered by a rechargeable Nickel-Metal Hydride battery with an integrated charger, delivering long operational uptime. Measurement data can be stored internally (128 KB memory) and transmitted via bi-directional RS232 interface for documentation and reporting.

Its robust design measuring 240 mm in length, 185 mm in width, and 110 mm in height, and weighing 3.4 kg, ensures durability in harsh environments such as construction sites, industrial plants, and maintenance workshops. The device includes safety leads, crocodile clips, and a carrying bag for convenient transport.
