Product Details

Testo Clamp Meter

The Testo clamp meter is a new age device that measures the current range between 0.1 to 600A AC/DC and voltage range between 1mV to 600VAC/DC. The user can fully retrace the movable pincer arm into an instrument for various functions such as tightly grabbing the packed cables in switching cabinets like a hook. This device helps in convenient measurements this in tight spots. The clamp meter also has a μA range as well an integrated temperature adapter for all type K thermocouples. It also offers a performance measurement function which can be connected with the Testo Smart Probes APP by Bluetooth. It includes the 3xAAA micro-batteries and 1 set of measuring cables.
