More details

High performance Gas Analyser

For NOx, SO2, CO, CO2, CH4, N2O and O2 gases.

Simultaneously and continuously measures up to 4 components out of NO, SO2, CO, CO2, CH4 and NO2 plus O2, making for a total of five components.

Hardly affected by interference of other gases.

The mass flow type twin detector of high sensitivity and reliability adopted makes measurement hardly affected by interfering components, ensuring a stable operation.
