Digital Clamp Meter 4000 Count

The ANENG ST181 is a digital clamp meter designed for electricians and DIY users who need to measure AC current up to 400 A, AC and DC voltage, resistance, capacitance, continuity, diode, frequency and live/zero wire detection. It uses a 4000-count auto-ranging display with backlight for clear readings in various lighting conditions. The tool suits commercial and household electrical troubleshooting tasks.

Battery Powered Operation

The meter runs on battery power so it is portable for on-site work without needing a mains connection. The clamp jaws open to a maximum of 1.42 inches, allowing measurement on conductors up to that diameter without interrupting the circuit. Non-contact voltage detection can be activated with a short press of the NCV button in any range for quick safety checks.

Compact Handheld Form Factor

The unit measures 10 L x 10 W x 2 H centimeters and weighs 0.6 grams, making it easy to carry in a tool bag or pocket for field use. The double open jaw design accommodates different operating habits during measurements. Note that the clamp measures AC current only and does not support DC current measurement.
