Measuring principle
●Oxygen (O2): Zirconia Sensors
●Combustible gas (COe): Solid-state electrolyte sensor
※COe：The sum of combustible gases (CO+H2+Cx+Hy) is considered as CO
Standard Features
●Clean flue gas (low dust) with a maximum flue gas temperature of 1000°C.
●Electronics, pushbuttons, and LCD display are assembled in a die-cast aluminum housing.
●Display of O2 and COe concentration values with 4-20mA output.
●Customized standard flanges such as ANSI, D IN, etc., with different lengths of guide pipes, the diameter of which is 60 mm. The flanges have connections for compressed air.
●The reference gas inlet is on the small flange of the connecting pipe, and the diameter of the flange is 100mm.
The power and signal lines (analog 4-20mA and digital RS-485 communication) are connected with robust industrial plugs.
