The testo 174 data loggers are designed for continuous monitoring of temperature- and humidity-sensitive goods in storage, refrigeration, and transport applications, while also enabling indoor climate monitoring. Ease of use simplifies day-to-day operations, and automatic data backup ensures complete and traceable documentation.
All four models feature an easy-to-read display and are HACCP-compliant. They can store up to 16,000 readings and allow freely selectable measurement intervals between one minute and 24 hours. The testo 174 T and T BT models measure temperatures from -30 to +70 °C and meet the requirements of EN 12830. The testo 174 H and H BT versions additionally measure relative humidity and temperatures from -20 to +70 °C. Depending on the model, data is either read out via USB-C and PC software or transmitted via Bluetooth to the testo Smart App.
