Infrared analysis module EIRma
The infrared gas analysis module EIRma is suitable for OEM applications and can measure CO, CO2, CH4, N2O, SO2, CF4, SF6, C4F8, CHF3, etc Each module measures one gas and one range, with selectable ranges from ppm to vol.%. Each gas can be measured in multiple different ranges. It has the advantages of high precision and low cost. Adopting dual beam technology to achieve long-term stable performance and reduce drift caused by light source aging. The module outputs analog linear signals and digital signals. Can implement RS-232 interface It can also provide a 4-20 mA or 0-10V linear output. Small size, suitable for a wider range of application needs
