If you are optimising energy usage, archiving, storing goods or creating a comfortable indoor climate &ndash;and if you can&rsquo;t analyze the temperature and humidity, you won&rsquo;t get optimal results. Testo 175 H1 is designed to carry out reliable long-term measurements and log these crucial values for you.

<br />
The testo 175 T1 temperature data logger is ideal for monitoring storage temperatures and long-term monitoring. It is certified for use in food environments and measures and logs temperatures constantly and reliably.

<br />
The temperature data logging with testo 175 T2 is ideally suited if you want to use single instrument to monitor air temperature and at the same time record additional temperature value on a second channel. It suits best for food storage for parallel temperature control of ambient conditions and the goods themselves.

The temperature logger testo 175 T3 with its two external thermocouple probes is best suited when for recording temperatures at two locations in parallel: for example when measuring the flow and return temperature on radiators. The readings are securely saved in the temperature logger and are available for later analysis and documentation.

Micro LR03 type alkali-manganese battery (AAA) with a voltage of 1.5 V. Suitable for the application range down to -10°C.
