The CA 6528 insulation tester is a high-performance electrical insulation resistance tester designed for professional electrical maintenance, diagnostics and testing of industrial electrical installations, including electric motors, cables and electrical equipment. Its ergonomic hands-free carrying design allows safe and efficient on-site testing, ideal for electricians and engineers across the UK.
This insulation testing device ensures enhanced electrical safety testing by automatically detecting dangerous voltage above 30 V, disabling insulation tests when external voltage is present. This makes it ideal for safe insulation testing in electrical installations and compliance with safety standards.
The CA 6528 megohmmeter performs insulation resistance tests at 250 V, 500 V and 1000 V, making it suitable for a wide range of applications. It delivers high performance with insulation resistance up to 11 GΩ, resistance up to 420 kΩ and voltage measurement up to 700 V AC/DC, in accordance with IEC 61557-2.
It also performs continuity testing with ≥200 mA test current, including automatic lead compensation for improved accuracy. With manual, locked and timed test modes, it is ideal for professional electrical testing and high-accuracy measurements.
The dual backlit display allows simultaneous viewing of insulation values and actual test voltage, ensuring excellent usability in all conditions. Colour-coded indication provides instant visual feedback when thresholds are exceeded.
This professional insulation tester UK is ideal for preventive maintenance of electrical systems. Regular insulation testing helps detect early degradation, preventing failures, reducing downtime and ensuring safety of personnel and equipment.
A reliable choice for professionals looking for a digital insulation tester for electrical installations, ideal for low and medium voltage insulation testing and compliance verification.
