The RTDTempX Series includes 4, 8, 12 and 16-channel RTD-based temperature data loggers. This series accepts 2, 3 and 4-wire RTDs to measure and record temperatures from -200 ºC to +850 ºC (-328 ºF to +1562 ºF) with a calibration accuracy of ±0.04 °C (±0.072 °F), all probe dependent.

The RTDTempX Series packs a memory capacity of 2,794,236 readings. To maximize memory capacity, users can enable or disable channels. There’s no interface necessary, the RTDTempX Series uses standard USB-A to Micro USB cable.


The RTDTempX Series is compatible with the latest MadgeTech 4 Software making starting, stopping, and downloading simple and easy. Graphical, tabular, and summary data is provided for analysis and can be viewed as customizable engineering units.
