testo 925 set met oppervlaktesensor temperatuurmeetapparaat 8714 0059

The testo 925 set combines a 1-channel temperature measuring instrument with a Type K thermocouple surface probe, offering a practical solution for surface temperature checks in heating, sanitation, and refrigeration work. Unlike basic thermometers, it provides audible alarm, min/max recording, and a backlit display for use in dim environments.

Highlights

• Includes surface probe for direct contact measurements on pipes and flat surfaces
• Wide instrument measuring range from -50 to +1000 °C
• Backlit LCD and audible alarm for convenient field use
• Long battery life of approximately 200 hours on a 9V block battery

In daily use

The instrument holds readings, tracks minimum and maximum values, and alerts you when a set threshold is exceeded. The included probe responds in about 5 seconds on metal surfaces and has a 1.2 m cable for flexibility.
