AI Technical Summary
In existing carbon monoxide detectors, the solenoid valve is prone to condensation and jamming in high humidity environments, leading to malfunctions in the control of the air inlet and outlet, and the entry of external moisture affecting measurement accuracy.
The outer shell is made of high-grade waterproof and dustproof material. Through the cooperation of the pump suction structure and sealing components, air is actively pushed into the measuring chamber. The air inlet and outlet are sealed when not in operation to prevent water vapor from entering. The reciprocating motion of the plunger is used to quickly measure the carbon monoxide concentration.
It improves the waterproof and dustproof performance of the measuring instrument, shortens the detection response time, extends the service life of the sensor, and enhances the accuracy and precision of the measurement results.
