Chauvin Arnoux C.A 6536 Specialist Megohmmeter – 10-100V Insulation & Continuity Tester

Overview
The Chauvin Arnoux C.A 6536 is a premium insulation and continuity tester designed for demanding environments such as aviation, space, defence, and other applications where precise, low-voltage insulation testing is required. It supports a variable test voltage ranging from 10 V to 100 V in 1 V increments, enabling users to tailor tests to specific insulation materials or standards. With a high insulation resistance capability up to 20 GΩ, the instrument also provides robust continuity, resistance, voltage, frequency, and diagnostic modes with high safety and ruggedness.

Engineered with safety and usability in mind, it features a safety rating of CAT IV 600V, ingress protection IP54 / IK04, and a rugged form factor. It is powered by six AA batteries, includes dual digital displays, and offers functions such as timer, lock, pass/fail alarms, and relative comparison (ΔREL) mode. Accessories include remote control probe, test leads, wire grips, and more. It is built for field engineers, maintenance teams, test labs, and procurement in high-spec sectors.
