Description
The testo 174 H BT mini data logger is suitable for monitoring the storage of temperature and humidity-sensitive goods such as foods or in archives, as well as for monitoring the climate in buildings. It precisely measures temperature and humidity in the range from -20 °C to +70 °C, displays current values and limit value violations and stores up to 16,000 readings. The data logger is easy to configure and evaluate using the free testo Smart App, which enables intuitive report generation and data evaluation via Bluetooth up to 30 meters distance.
The automatic data backup ensures reliable measurement data acquisition, even when the battery is empty or has been replaced.
