The MicroRHTemp is a humidity and temperature data logger that can fit in the tightest places. Standing only 1.5 in. (39 mm) tall and 0.6 in. (16 mm) in diameter, it’s even small enough to fit into most pill bottles.

This device may be tiny, but it’s powerful. The MicroRHTemp measures and records temperatures from 0 °C to +60 °C (+32 °F to +140 °F) with an accuracy of ±0.5 °C. The MicroRHTemp can store up to 32,766 readings and is equipped with an LED alarm indicator that alert when user-specified temperature limits are exceeded.

The MicroRHTemp 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.
