testo 176 T1 Highly Accurate pt100 Logger


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 over a longer period of time. The fact that its metal housing is extremely robust makes the data logger particularly suitable for monitoring the temperature in industrial environments. 

The Testo 176 T1 single channel data logger is ideal for high-precision temperature monitoring. Its internal sensor records the indoor air temperature. Its sensor is a Pt100 temperature sensor, which means that the temperature is measured and documented with extreme precision. The Pt100 temperature sensor can achieve an accuracy of up to 0.2 °C.

The temperature data logger's has the ability to store up to 2 million readings. Temperature can therefore be monitored over a long period of time, without the need for frequent data logger read-out. Its battery life of up to 8 years at a 15 minute measuring rate also offers considerable advantages for long-term temperature monitoring and recording.

Technical features and practical benefits

The 176 T1 temperature data logger has a metal housing, which is an advantage for temperature monitoring in the industrial sector. The data logger can therefore be used for long-term measurements, even in extreme conditions. The temperature data logger is also completely water and dust-proof in compliance with protection class IP 68.


The measurement data is stored securely on the testo 176 T1 – it will not be lost, even if the battery's depleted or changed.

The temperature data logger is tested and certified for use in the food industry by the ATP test station at TÜV Süd in accordance with DIN EN 12830. It is also HACCP-certified.


Possible areas of application for the temperature data logger
