COMBUSTION GAS ANALYSER

For continuous measurement of oxygen and/or combustibles (COe) and enable increased combustion efficiency

• Unique close coupled, low extracted volume design protects sensors and provides fast, in-phase O2 and COe measurement without probe blockages
• Long life, low drift zirconia and catalytic sensors
• Protective, BASEEFA tested flametraps as standard
• Wide variety of probes and flanges
• Configurations for safe or hazardous area use
• Proven applications include power generation boilers, process heaters, thermal crackers and incinerators
