This compact round digital thermometer and hygrometer is ideal for monitoring environmental conditions when storing 3D printing filaments and materials. Used together with 3D-printed desiccant boxes or dry boxes, it provides continuous temperature and humidity monitoring inside the storage space.

The precisely sized housing allows easy installation into a dedicated slot in a printed enclosure, where it fits securely and remains clearly visible. The LCD display shows real-time data, and the device features a fast response with a measurement cycle of about 10 seconds.

Temperature measurement range is –50 °C to 70 °C, humidity range 20–90% RH. Units can be switched between °C and °F using the rear button. Powered by 1× LR44 (1.5 V) button cell battery.
