CEM DT-9280 AC/DC True RMS Clamp Meter

The CEM DT-9280 AC/DC True RMS Clamp Meter is another model from CEM, designed to provide accurate electrical measurements for both alternating current (AC) and direct current (DC) systems. This model also incorporates True RMS technology for precise measurements regardless of waveform distortions. True RMS meters are particularly valuable in industrial environments where equipment often generates electrical noise and non-linear loads.

Such clamp meters are invaluable tools for electricians, HVAC technicians, and maintenance personnel who need to perform reliable and safe measurements in both residential and industrial settings. They provide a non-invasive method of measuring current, which is safer and quicker than traditional methods that require circuit interruption.
