The data logger for temperature measurement - testo 176 T3 features a robust metal housing which makes it suitable for use in the industrial and trade sector, e.g. for process monitoring. You can measure the temperature at up to four points simultaneously – e.g. to measure the flow and return temperatures on radiators. Up to four thermocouple probes can be connected to the data logger (temperature probes TC Type K, Type T or Type J). You can select the thermocouple probes from our large probes range and order them when purchasing the data logger.

The advantage of thermocouple probes is that they react very quickly and cover a large measuring range. For example, you can record particularly low temperatures (as low as -195 °C) using a temperature probe TC Type K – depending on the model selected – or you can even carry out high temperature measurements (up to +1,000 °C). This enables you to take measurements in super freezers and also monitor high-temperature industrial processes.

The data logger for temperature measurement - testo 176 T3 records up to 2 million readings and can therefore be used for long-term measurements, eliminating the need for the data logger to be read out overly frequently. The data logger has a battery life of up to 8 years, which also makes it a practical instrument for long-term measurements.
Technical features and practical benefits

The testo 176 T3 data logger for temperature measurement has a metal housing, so it is well-equipped for industrial applications. The housing of the data logger means that it is extremely robust and, in conformity with protection class IP 65, also protected against dust ingress and water jets. The data logger can therefore be used in polluted and dust-laden environments. When carrying out cleaning at the measuring location, you do not need to remove the data logger.


When using the data logger for temperature measurement, you can rely on a high level of data security. Measurement data that you have saved will not be lost, even if the battery is spent and being replaced – which is something you can carry out yourself.

Possible areas of application for the data logger for temperature measurement
-  Monitoring and recording the temperature in deep-freezers or in cryogenic conditions
-  Monitoring and recording the flow and return temperature of heating systems
-  Monitoring and recording process temperatures
-  Measuring and documenting flow and return temperatures at the distributor of an underfloor heating system in order to ensure functional capability


Programming and analysis of the data logger for temperature measurement

In order to program and read your data logger and analyze your temperature measurement data, you need to use a software package. There are three software versions to choose from:

-  ComSoft Basic software – available free of charge (as a download) – is used for quick programming of the data logger and for easy data analysis

-  ComSoft Professional software – available to order subject to a fee – provides you with multiple options for detailed analysis of the measured temperature values

-  ComSoft CFR 21 Part 11 software – available to order subject to a fee – is ideal for use in the pharmaceutical industry with its special requirements according to CFR 21 Part 11

The data logger for temperature measurement is programmed and read out by means of a USB cable, which is not included in the delivery. You can also use the cable to transmit the measurement data to your PC. You also have the option of using an SD card for this. You can order both when purchasing your data logger.
