Professional heating measurement technology for every requirement.

The testo combustion gas analyser series consists of three analysers, The testo 310, Testo 320 & Testo 330 series. These analysers come with an integrated NOx filter which eliminates cross-sensitivity errors of CO measurements. In addition these analysers come CO over range protection which prevents the gas analysers form overranging the CO sensor. 

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.

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

Tightness and leakage

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

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

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
