The testo 320 basic features all the essential functions for carrying out flue gas analysis on domestic heating systems, including flue draught, pressure measurements, and differential temperature measurement. The flue gas analyser is easy to use with its full colour graphic display featuring a user-friendly menu guidance. The analyser measures both O2 and CO (4,000ppm sensor fitted as standard) and can also display calculated parameters such as combustion ratio, CO2, etc.

Designed for domestic boiler service, the testo 327 offers users a rugged and reliable instrument for flue gas analysis and measurement. 
 
This kit also includes the new testo gas leak detector which allows simple and effective leak detection of methane, propane, butane, and hydrogen gases. 
 
Additionally included in this kit are a set of CPA1 / BS7967 probes for CO testing of cookers and flueless appliances.
