Martindale CMi210 Insulation Tester & TRMS Clamp Meter
What is the Martindale CMi210?
The Martindale CMi210 is designed for electricians and electrical maintenance technicians who need a single instrument for insulation testing, electrical measurements and high-current clamp measurements. Combining a True RMS AC/DC clamp meter with a 1000 V insulation tester, it reduces the number of tools required for installation, commissioning and preventative maintenance.
Complete Electrical and Insulation Testing
The CMi210 measures AC/DC current up to 2000 A, AC/DC voltage up to 1000 V DC / 750 V AC, insulation resistance up to 6 GΩ, resistance, continuity, capacitance, frequency and temperature. Its large 57 mm jaw accommodates sizeable conductors, while the built-in insulation test voltages of 50 V, 100 V, 250 V, 500 V and 1000 V make it suitable for testing motors, cables and electrical installations.
Built for Professional Electrical Testing
Designed for demanding industrial and commercial environments, the CMi210 features a CAT IV 600 V / CAT III 1000 V safety rating, live circuit detection and automatic discharge after insulation testing for added user protection. How does the CMi210 improve productivity? It combines insulation testing, clamp measurements and multimeter functions into one rugged instrument, helping electricians complete more work with fewer tools.
