Are the prescribed humidity and temperature values in warehouses and buildings being adhered to? Is mould in the apartment the result of insufficient ventilation, or caused by building damage? With the data logger for temperature and humidity testo 176 H1, you can find out.

Up to two temperature and/or temperature/humidity probes can be connected to the 4-channel data logger testo 176 H1 and positioned in the room according to the individual requirements. A wide selection of probes is available to you for this purpose.

The lock included in delivery protects your temperature and humidity loggers from unauthorized access.

The testo 176 H1 data logger for temperature and humidity guarantees high data security and reliable measurement results on the basis of modern measurement technology.

In addition to the current temperature and humidity values, the data logger testo 176 H1 also shows the dewpoint in the display (when a temperature/humidity probe is connected). You can read programmed limit values, min., and max. values, limit value violations as well as the remaining battery life easily from the large display. It is therefore not necessary to read out the temperature and humidity logger to a PC in order to gain a quick overview.

Thanks to the large memory for 2 million measurement values, and the battery lifetime of up to 8 years, you can read out the data much less often, even at shorter measurement intervals. The standard battery (AA) can be easily exchanged at any time by the user.

  • 4-channel data logger for temperature and humidity testo 176 H1 with external probe connections (NTC/capacitive humidity sensor), including wall bracket, battery and calibration protocol.
