-
Using NDIR (Non-dispersive infrared measurement), the sensor is not in contact with the measured gas, and the poisoning of the sensor will not occur;
-
High stability infrared light source and filter with strong anti-interference ability make the analyzer have good long-term stability;
-
With microprocessor as the core, it has the characteristics of intelligence, good stability, high precision and long calibration cycle.
