Combustion Analysis - Smarter and more brilliant than ever!

The New 3-Gas, Testo 300 combustion analyzer measures O2, CO and optional NO (calculated NOx), draft efficiency excess air, with proven sensor technology and now incorporates and transmits data via the new generation of connectivity.  Take it for a test drive so you can experience the:     

  • Brilliance you can touch
  • Bluetooth, WiFi and smart phone communications to Connect to your smart world
  • Long life sensor that last up to 6 years
Testo fine particle measuring instrument

Combustion gas & particle analyzer for biomass fueled applications

The Testo 380 integrates the measurement of the gaseous combustion parameters (ie. O2, CO and CO2) particulate mass (PM), in one simple-to-use package. The system provides all measurements in real-time and includes data logging capability through powerful software. Simultaneously measuring both fine particulate and the combustion parameters set a new standard in combustion instrumentation.

The testo 380 is solely designed to measure the combustion parameters and particulates from biomass fueled combustion sources.  The solid fuels include:

  • Wood pellets/logs/wood chips/wood briquettes (and wood refuse)
  • Straw and grains
  • Coal, coal briquettes, coke, brown coal, lignite and peat
