MD 9272 Leakage Clamp TRMS Meter with Power Functions
MD 9250 Industrial TRMS AC/DC CAT IV /1000 V
The MD 9272 is a unique earth leakage clamp meter. It not just has the ability to accurately read the TRMS AC leakage
current of a system, it can also detect losses in the system and suggest possible reasons for the loss. The voltage, power,
harmonic, power factor (PF), total harmonic distortion (THD) and crest factor measurements make this instrument suitable
for any electrician and engineer.
The MD 9250 is the first Clamp Meter that meets overvoltage category CAT IV 1000 V. MD 9250 is a high quality clamp
meter specially designed for single-hand operation, built-in measuring functions; TRMS AC/DC (current, voltage), capacitance, temperature and full range resistance makes this instrument an ideal tool for the most demanding applications in
the industrial sector. The large jaws capacity of (max. 55 mm) in diameter allows AC/DC - current measurements up to 2000
A. High resolution and accuracy, 2-line LCD display fast data acquisition and transfer (via optical interface), non-contact
voltage detection, and auto-check function are highlights of the instrument.
