The GA220 is a multi gas analyzer for continuous online measurement of up to 6 process gases, with up to 8 sample gas inlets for several measuring points. It combines infrared, electrochemical and zirconia sensors in one 19-inch unit, so oxygen (O2), hydrogen sulfide (H2S) and hydrogen (H2) are measured together with IR-active gases such as perchloroethylene, the refrigerants R11 and R12 or cyclopentane. Mutual interference between the gases is compensated.
Typical applications:
- Chemical industry: monitoring reaction and process gases
- Recycling: solvents and refrigerants
- Pharmaceutical production
- Environmental technology and safety monitoring
- Multi-stream monitoring where several sample points share one analyzer
What operators get:
- One process gas analyzer instead of several single gas devices
- Up to 8 sample gas inlets for multiple measuring points
- Patented NDIR method with reference pressure measurement, cuvette heated to 50 °C, pressure compensation
- RS232 as standard; Profibus DP, Modbus TCP, EtherNet/IP, Profinet and up to 8 isolated 4–20 mA outputs as options
- Optional sample gas filter and pressure regulator for inlet pressures up to 100 bar
