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 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.

Ideal for use in temperatures below -10&nbsp;&deg;C. Replacement of the lithium batteries is rarely required as they have a long life.
