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.

Features

• 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
