CM100 Flexible True RMS AC High Current Flex Clamp Meter


The CM100 is a clamp meter with a flexible current sensor capable of measuring true RMS AC current up to 3000A in 3 ranges (30A, 300A, 3000A). The flexible current sensor is beneficial for the measurement of different sizes and shapes of conductor which cannot be measured with a standard clamp meter. It's a popular choice for electricians, technicians, and engineers who need a reliable and versatile tool.

Features and Benefits:


• Flexible sensor - designed for measuring current in tight spaces or around awkwardly shaped conductors

• Lightweight and simple to use with Min/Max Indication, Display Hold, Auto Power Off and Display Backlight.

• True RMS measurement - accurately measures AC current, even on distorted waveforms caused by modern electronics and non-linear loads.

• Backlit display - easy to read in low-light conditions.

• Auto power off: Conserves battery life

• AC Current: 10mA to 3000A (in 3 ranges)

• Accuracy: 3.0% of readgin + 5 digits (45 - 50Hz)

• Operating Environment: 0°C to 50°C <80% RH, non condensing

• Pollution Degree: 2

• Probe Cable Length: 18" (45.8cm)

• Probe Cable Diameter: 8.35 nominal

• Cable Length (probe to meter): 1.8 m

Supplied with

2 x 1.5V AAA batteries and instructions
