CEM DT-9889 True-RMS Thermal Digital Multimeter, Wireless (PC / App)

A multimeter with integrated thermal imaging is a hybrid diagnostic instrument that consolidates two essential tools into a single device:

A digital multimeter (DMM) for measuring electrical parameters.

A thermal imager (infrared camera) for detecting temperature variations and visualizing heat patterns.

This dual-function capability enables technicians to simultaneously assess thermal conditions and electrical values, thereby enhancing both the speed and safety of troubleshooting.

As main use for True-RMS Thermal Digital Multimeter

First, use the thermal imager for a wide-area scan to quickly pinpoint abnormal hot spots; then use the multimeter function for targeted measurements to accurately diagnose the cause. This approach is significantly more efficient than switching back and forth between two separate sets of tools.
