testo 922 - Differential temperature measuring instrument for TC Type K with App connection

Order-Nr.  0563 0922

  • Easy, fast and precise differential temperature measurement with dual thermocouple Type K probes (2 TC Type K probes 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 -50 °C to 1000 °C

  • Large probe selection optional and compatible with commercially available TC Type K sensors

With the compact 2-channel temperature measuring instrument testo 922 (dual TC Type K, 2 probes included) you have the versatile solution for simple, fast and precise measurement of the differential temperature, e.g. when checking the supply/return temperature on heating circuit manifolds. The testo Smart App supports you with useful functions suchz as configuration, display (also as second screen) and storage as well as documentation of the measured values directly in the App.

Product Description

Professionals in industry and trade value the compact differential temperature measuring instrument testo 922 for its versatility: it not only determines temperatures quickly and accurately, but also does a direct calculation of the differential temperature. And that’s in a wide measuring range from -50 °C to 1000 °C. This means that measurements can be completed just as quickly as documentation with the practical testo Smart App for smartphones and tablets. A typical application for the testo 922 is, for example, the control of the supply/return temperature on heating circuit manifolds. Two Type K thermocouple probes are included, but the testo 922 is also compatible with other commercially available TC Type K probes. Incidentally: The testo Smart App not only supports you with the documentation of your measurement results. The smart assistant also takes care of configuring the testo 922 and displaying and storing the measured values for you. A particularly practical feature: The App also turns your smartphone into a second display.
