Professional heating measurement technology for every requirement.


Testo manufacture an extensive range of quality measurement equipment for the heating sector. Measurement parameters include Flue gas, Temperature, CO, and CO2.

Whatsmore, with testo's new smart tools, you can save measurements to your Smart Phone or tablet via Bluetooth, and send results to your customer there and then as a report.

Flue gas analysis

Flue gas and emission measurement on heating systems and other small combustion plants serves to determine the level of pollutants emitted and the heating energy lost.

  • The atmosphere should be contaminated as little as possible by pollutants.
  • Energy should be used as efficiently as possible.

Measurement technology for heat pumps

At Testo, you’ll find the right measurement technology for a cost and energy efficient operation of heat pumps. You also make sure the environment isn’t burdened by any leaked refrigerant. 

  • Pressure and temperature testing
  • Controlled refrigerant service
  • Easy tightness testing and evacuation

Differential pressure measurement

Gas pressure testing on burners is one of the standard measurements during services of domestic heating systems. This involves measuring the gas flow pressure and gas resting pressure.

  • Optimum flow pressure in gas burners in the range form 18 to 25 mbar
  • Avoid heating system breakdown

Temperature measurement

Whether for flow and return temperatures, for radiators and underfloor heating system or for indoor air: Testo offers the entire range of temperature measuring instruments for heating contractors.

  • Large range of probes for max. flexibility
  • Optimally calibrated and norm-compliant measuring instruments

Electrical measurement parameters

User-friendly measuring instruments with easy handling ensure precise and secure measurement of electrical parameters such as current, voltage or resistance.

  • Innovative multimeters, clamp probes, current testers and voltage testers
  • Testing of ionization flow in gas burners

Leakage test

Tightness testing (better known as serviceability or leakage quantity testing) on pipe systems must be repeated every 12 years with a measuring instrument.

  • Testing drinking water pipe according to ZVSHK EN 806-4
  • Gas testing according to DVGW G5952, TRGI 2008 G600

Ambient CO measurement

Carbon monoxide (CO) is a dangerous gas. For this reason, the ambient CO contamination must be regularly checked at combustion sites where it can occur.

  • Secure CO measurement in seconds
  • CO zeroing at the measurement site
