testo 0615 1912 Surface Probe NTC -50 to +150 °C

Measuring surface temperatures in tight or awkward spots can be challenging with standard probes. The testo 0615 1912 Surface Probe solves this by providing a compact NTC sensor that delivers accurate readings from -50 to +150 °C, making it ideal for HVAC, industrial maintenance, and laboratory applications.

Who is it for

This probe is built for technicians and engineers who need reliable surface temperature measurements on pipes, motors, or flat surfaces. It pairs with compatible testo measuring instruments, offering a practical solution for routine diagnostics and quality checks.

Main features

• NTC sensor type for fast response and stable readings
• Wide measurement range: -50 to +150 °C
• Compact design for easy handling and storage
• Compatible with select testo instruments (verify instrument compatibility)

Tips

For best accuracy, ensure the probe tip makes full contact with the surface and allow a few seconds for the reading to stabilize. Avoid measuring moving or electrically live surfaces unless properly insulated.
