Overview
Gasboard-3050 is a flue gas oxygen and humidity analyzer that uses a ceramic zirconia sensor to calculate and output O2 concentration and humidity. With a heated, filtered stainless-steel detector, it is suited to hot, humid flue gas in online CEMS, and provides status/alarm contacts, 4-20 mA output and RS232/RS485.
Key Features
- Capable of measuring O2 & humidity simultaneously.
- Detector with heating function, to prevent water condensed on detector.
- Detector is made of stainless steel, corrosion resistant, which could be used in harsh conditions.
- Detector is with filter to prevent PM/dust to block the detector
- With running indicator and error/ alarm switching value output, to monitor the running state of analyzer
- With 4~20mA analog output and RS232/RS485 communication interface, conveniently integrated
