The ZE08-CH2O is a versatile and compact electrochemical formaldehyde detection module. It employs the electrochemical principle to detect formaldehyde (CH2O) in the air, endowing the module with high selectivity and stability. A temperature sensor is integrated to perform temperature compensation. It features both digital output and analog voltage output simultaneously. It represents a blend of a well - established electrochemical detection principle and a refined circuit design.
Applications :
- Portable detector
- air-quality monitor
- air cleaner
- air renewal system
- air conditioner
- smart home
