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.

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.

The 4-channel data logger testo 176 H1 allows the monitoring of temperature and humidity in warehouses and buildings. With the testo 176 H1, you can examine whether mould in a house or apartment has been caused by insufficient ventilation or by building damage.

The robust metal housing of the testo 176 H2 climate data logger protects it against mechanical impacts. Data logging of temperature and humidity can be done even in harsh environmental conditions.

When ambient conditions, for example in a laboratory, need to be documented securely and highly accurately, the testo 176 P1 is the right data logger. It has an integrated absolute pressure sensor and connection possibilities for two external temperature/humidity probes (optional).

The testo 176 T1 data logger monitors the temperature, even in extreme conditions, with a highly accurate Pt100 temperature sensor. It is able to precisely document the temperature status over a longer period of time. Its robust metal housing makes it particularly suitable for industrial environments.

With two inputs for external Pt100 probes, testo 176 T2 temperature data logger can record temperature at two measuring points simultaneously. It means that it can monitor temperature at different locations in parallel. The temperature logger has a large display for optimum presentation of the readings.

The testo 176 T3 data logger for temperature measurement is ideal for monitoring temperature values in production processes. Its robust metal housing makes it ideal for use in the industrial sector. With inputs for four thermocouple probes, it can measure at up to four points in parallel.

The testo 176 T4 temperature data logger can measure the temperature at upto four different measurement sites simultaneously. It has a super size memory for upto 2,000,000 readings and is compatible with a number of different thermocouples making it ideal for professional use in a variety of fields.
