FNIRSI MC-40 Digital Clamp Meter Multimeter

The FNIRSI MC-40 is a compact and intelligent true RMS digital clamp meter designed for accurate electrical measurements in professional and DIY environments. It allows users to measure AC current up to 600A without breaking the circuit, making it ideal for electrical maintenance, installation, and troubleshooting.

With automatic range detection, 6000 count digital display, and true RMS measurement, the MC-40 provides reliable readings even on non linear electrical loads. The meter also includes useful functions such as non contact voltage (NCV) detection, resistance measurement, diode testing, and continuity testing, making it a versatile tool for everyday electrical diagnostics.

Its ergonomic clamp design with a 26mm jaw opening, backlit display, and built in flashlight ensures easy operation even in tight or low light environments.
