Principle
The instrument adopts the pump-suction Sampling method, and the environment gas is sucked into the inside of the instrument through a built-in powerful air pump. The gas passes through a reasonably designed gas chamber and is in contact with the built-in imported electrochemistry/infrared absorption gas Sensor. The Sensor converts the gas concentration signal into an electrical signal, which is processed, calculated and temperature compensated by a 24-bit ADC data collection chip and a 32-bit microprocessor. Finally, the gas concentration value is displayed in real time on the 3.5-inch IPS industrial color screen. The instrument supports a variety of concentration unit conversions and automatic range switching.
