The Martindale CM100 True RMS High Current Flex Meter is designed for commercial and industrial electricians who need to measure high AC currents safely around large conductors and busbars. Its flexible Rogowski coil makes it easy to access confined spaces where conventional clamp meters cannot fit, making it ideal for switchgear, distribution boards and industrial electrical installations.
High Current Measurement Made Simple
With a measurement range of 30 A to 3000 A AC, the CM100 provides accurate True RMS readings on non-linear loads commonly found in modern electrical systems. The lightweight flexible sensor wraps easily around large conductors up to 160 mm diameter, while the compact handheld display keeps readings clear and accessible during testing.
Built for Everyday Electrical Testing
Whether you're carrying out electrical maintenance, diagnosing load issues or performing routine inspections, the CM100 offers reliable high-current measurements in a portable design. Why choose a flexible clamp meter? The flexible coil provides easier access around oversized conductors and awkward installations where traditional rigid clamp meters cannot be positioned.
