M-900C Combustion analyzerDetailed product description：

The M-900 combustion analyzer is a portable instrument specifically designed for analyzing the composition of flue gas from stoves, water heaters, and various gas equipment. It can simultaneously measure the values of oxygen (O2), carbon monoxide (CO), and carbon dioxide (CO2) in flue gas (measured values). Complies with the new national standard GB16410-2007. The instrument has stable performance and high reliability, with self calibration upon startup, fault prompt function, and a fully localized Chinese human-machine dialogue interface. It is a multifunctional and intelligent analytical instrument that is particularly suitable for scientific research, testing, and production control.
Instrument features:
Adopting a high-end carrying case, it is small in size, portable and sturdy (300 × 160 × 190mm).
Adopting microcomputer technology, the instrument has functions such as self checking and automatic calibration;
The instrument adopts a fully Chinese interface to achieve human-machine dialogue and automatically prompt the working status and operation steps of the instrument.
Adopting a new generation of imported sensors, it has fast response, high accuracy, good stability, and long service life. The O2 sensor can be used for about 2 years, and the CO lifespan is about 5 years.
Measure CO2 using a thermal conductivity gas sensor.
The instrument is equipped with a rechargeable battery, which can work continuously for 6-8 hours when fully charged. It can also work directly with an AC 220V power supply. The unique "step frequency response" technology greatly improves the response speed of the instrument, which is 2-3 times faster than similar products. The test can be completed in about 30 seconds at a time.
16 sets of on-site test data can be randomly stored.

Main performance parameters:
Measurement range:
Oxygen (O2): 0-25%
Carbon monoxide (CO): 0-2000ppm
Carbon dioxide (CO2): 0-15%
CO '(α=1): 0-9999ppm (calculated value) (converted value of CO based on the old standard α=1)
CO’=CO×(20.9/20.9－O2)
According to the new standard GB16410-2007, the calculation method for CO1 is as follows: CO1=C1a × (C2max/C2a-C20)
Where:
C1- concentration of carbon monoxide in dry flue gas, theoretical air coefficient α=1, volume percentage;
C1a - Measurement value of carbon monoxide concentration in dry flue gas, volume percentage;
C20- Measurement value of carbon dioxide concentration in indoor air (dry state), volume percentage;
C2a - Measurement value of carbon dioxide concentration in dry flue gas, volume percentage;
C2max - theoretical concentration of carbon dioxide in dry flue gas (calculated value), volume percentage;

Measurement accuracy:
Oxygen (O2): ± 0.2% O2
Carbon monoxide (CO): ± 5% ± 5ppm of the reading value
Carbon dioxide (CO2): ± 0.3%
CO '(α=1): ± 5% ± 5ppm of the reading value (calculated value)
