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.

• 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
