Testo 330-1G LL is no longer manufactured.

Today I am reviewing the 330-1G LL Combustion Analyzer with Color Graphics from Testo. The Testo 330-1G LL is designed to measure O2, CO, (NOx option), draft & temperature (ambient & flue) in addition to calculations of CO2, efficiency, excess air, and CO air free. This can be exceptionally useful for emissions monitoring, maintenance and tuning of combustion processes such as burners, boilers, diesel and gas engines, laboratory analysis, heaters, kilns, furnaces, turbines, water heaters, and more.
