0563 0925 925 - Temperature Measuring Instrument for TC Type K with App connection by Testo

Hardly any measurement value is measured more often every day than temperature. The quality of products, processes or raw materials depends on it, as does the efficiency of plants.

This makes it all the more important that you have a compact measuring instrument at hand for temperature measurements that show what you need to know simply, quickly and precisely. A measuring instrument like the testo 925 convinces not only by the large measuring range (-58 to 1832 °F), its handling, robustness and the smart support via the testo Smart App will also inspire you.

One Type K thermocouple probe is included in delivery. However, the testo 925 is also compatible with other commercially available TC Type K probes.

The testo Smart App supports you in your work with the testo 925 with these practical functions:

• Configure measuring instrument
• Display graphical measured value curve
• Save measurement data
• Manage customers and measuring points
• Documentation on site
• E-mail dispatch of the report
• Second Screen display

• Easy, fast and precise temperature measurement with thermocouple Type K probe (1 TC Type K probe included)
• Fast in-app configuration, graph history, second screen and measurement data memory in the testo Smart App
• Wide range of applications due to large measuring range from -58 to 1,832 °F
• Large probe selection optional and compatible with commercially available TC Type K sensors
• Audible alarm sounds if a limit value is exceeded
