The compact heating set with the testo 115i clamp thermometer, the testo 510i differential pressure measuring instrument and the testo 805i infrared thermometer is ideal for important measuring tasks performed by heating engineers.

The advantages of the heating set

In conjunction with your Smartphone or Tablet, all heating system temperatures and pressures can be measured and checked. The handy testo Smart Case provides optimum protection for the measuring instruments and means that they are always to hand when they are needed.

It allows you to remotely read measurements from up to six (6) Smart Probes and easily document/report the results

Advantages and applications of the individual measuring instruments

testo 115i clamp thermometer

- Particularly practical for temperature measurements at widely spaced measuring points
- Measurement of the flow and return temperature

testo 510i differential pressure measuring instrument

- Measurement of the differential pressure, as well as the gas flow pressure and static pressure
- Pressure drop test
- Measurement of the air flow velocity
- Measurement of volume flow

testo 805i infrared thermometer

- Laser circle to mark a measuring spot
- Non-contact measurement of surface temperatures

Practical App with special functions for measurement data analysis on your Smartphone or Tablet

Measurement data is transmitted wirelessly from the relevant measuring instrument to the Smart Probes App and can be viewed conveniently on mobile terminal devices – either as a chart or in table form. The App also offers practical functions such as timed and multi-point mean calculation, volume flow configuration or a pressure drop test. The measurement data log can be emailed directly as a PDF or Excel file. This saves you time, allowing you to further increase your efficiency.
