testo 176 T2 PT100 Two Channel Logger

With its two inputs for external Pt100 probes, the Testo 176 T2 temperature logger can record the temperature at two measuring points simultaneously. This makes it possible to monitor temperature at different locations simultaneously. The data logger features a large display for easy readouts.

The Testo 176 T2 temperature logger is particularly suitable for areas / applications which require dual temperature measurements. The data logger can accommodate two Pt100 probes of your choice, a range of probes compatible with the 17tT2 can be found in the accessories section. It is therefore possible to safely store temperature values from different measuring locations and, if required, compare them on site on the logger display.

You can carry out temperature monitoring over a longer period of time. The testo 176 T2 temperature logger can store up to 2 million readings. Its battery life of up to 8 years also makes it practical for long-term temperature monitoring.


Technical features and practical benefits

The logger display offers you an overview of the current readings, limit values set and limit value violations, minimum and maximum values and also the remaining battery life. Thus, there is no need to read the data logger separately on your PC in order for quick analysis.  

Data security is our top priority: you can rest assured that the measurement data stored in the temperature logger will not be lost. Data is not lost, even when the logger's battery is depleted or while you are replacing the battery.

The temperature logger is suitable for use in the food industry: it is certified to EN 12830 (tested by the ATP test station at TÜV Süd) and is HACCP Certified. In compliance with protection class IP 65, the data logger is protected against water jets and can remain at the measuring location while cleaning is carried out there.

Possible areas of application for the temperature logger

Temperature monitoring and documentation in storage facilities

Temperature monitoring and documentation in deep-freeze storage areas, for example for foodstuffs

Temperature monitoring and documentation in cold storage areas or in refrigerators, for example in pharmaceutical refrigerators

Temperature logger as a reference for calibrating another temperature logger


Programming and analysis of the data logger 

Programming and reading the data logger, as well as the analysis of measurement data, requires the use of a software package. Three different software versions are available:

 ComSoft Basic software – available as a free download – is ideal for fast programming of the temperature logger and easy data analysis

 ComSoft Professional software – also available – offers various options for carrying out detailed analysis of the temperature values

 ComSoft CFR 21 Part 11 software – also available – designed for applications in the pharmaceutical industry with its special requirements according to CFR 21 Part 11
