MAX100-BTU Real-Time
Heating Value Gas Analyzer

MAX100-BTU Real-Time Heating Value Gas Analyzer

The MAX100-BTU provides a rapid, high precision measurement of heating value and gas composition for optimal combustion control and environmental compliance.
The MAX100-BTU uses cutting-edge quadrupole mass spectrometer technology to deliver a continuous online analysis of fuel gas and vent streams containing hydrocarbons, H2, CO, CO2, H2O, H2S and other gases. It has the speed necessary to analyze the total composition of the sample and report the Heating Value in seconds.
