ENCEL M-900C ເຄື່ອງວິເຄາະການເຜົາໃຫມ້ (O2: 0-25%/ CO2: 0-15%/ CO: 0-2000ppm)

Measuring range:

Oxygen (O2 ): 0 to 25%

Carbon monoxide (CO): 0 to 2000 ppm

Carbon dioxide (CO2 ): 0 to 15%

CO' ( α=1) : 0 to 9999 ppm (calculated value) (CO' system CO conversion value when the old standard α=1,)

CO'=CO×(20.9/20.9-O2 )

According to the new standard GB16410-2007, the calculation method of CO1 is as follows: CO1 =C1a × (C2max /C2a -C20 )

where:

C1 - Carbon monoxide concentration in dry flue gas, theoretical air coefficient α = 1, volume percentage;

C1a - measured value of carbon monoxide concentration in dry flue gas, volume percentage;

C20 - measured value of carbon dioxide concentration in indoor air (dry state), volume percentage;

C2a - measured value of carbon dioxide concentration in dry flue gas, volume percentage;

C2m ax ——Theoretical carbon dioxide concentration in dry flue gas (calculated value), volume percentage;

Measurement accuracy:

Oxygen (O2): ± 0.2% O2

Carbon monoxide (CO): ± 5% of the reading value ± 5ppm

Carbon dioxide (CO2 ): ± 0.3%

CO' ( α = 1) : ± 5% of the reading value ±5ppm (calculated value)
