•Practical for frequent and long-term measurements: memory capacity of 1 million readings, up to 3 years’ battery life •Very large temperature measuring range from -50 °C to +1 000 °C •Including wall bracket •Measurement data analysis and documentation: three different software versions to choose from, basic software available as a free download The testo 175 T3 temperature logger with its two connections for external thermocouple probes is a good idea when you would like to record your 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 measurement data analysis and documentation. Product Description The testo 175 T3 temperature logger is equipped with two connections for external thermocouple probes (type T or type K). This means the data logger is ideally suited for carrying out temperature recording on two channels. This is for instance necessary, if you want to check that a heating system is working properly. To do this, the temperature logger measures the flow and return temperature simultaneously. The data logger can likewise be used in industrial production control, if process temperatures need to be checked at different locations. State-of-the-art measuring technology, high level of data security You can select the external thermocouple probes from our wide range of probes and order them to go with the data logger. This gives you flexibility and means you can decide yourself exactly what your temperature logger has to be capable of doing.
