The robust metal housing of the testo 176 T3 temperature data logger 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 both take measurements in super freezers and also monitor high-temperature industrial processes.

The memory of the temperature data logger 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.

The testo 176 T3 temperature data logger 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 temperature 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 logger.

When using the data logger, 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.
