Metravi’s clamp meters are True RMS instruments built to measure both AC and DC current without breaking live circuits. Utilizing Hall-effect sensors and insulated clamps, they offer safe and accurate clamp-on measurements up to 1,500 A (on appropriate models) 

A Digital Clamp Meter is an electrical testing instrument that combines a basic digital multimeter with a current sensor. It allows non-intrusive current measurement—meaning you can measure current in a conductor without physically disconnecting or cutting the wire. This is done by clamping the jaws around the conductor, making it ideal for live current monitoring in residential, commercial, and industrial settings.

HTC Instrument offers several True RMS digital clamp meters that combine comprehensive measurement functions with safety features like non-contact voltage detection and backlit displays.

An AC/DC Clamp Meter is a multifunctional handheld testing instrument designed to measure electric current flowing through a conductor without direct contact or circuit interruption. It uses clamping jaws to detect current via electromagnetic induction and Hall Effect sensors—making it ideal for both Alternating Current (AC) and Direct Current (DC) measurements.
