ماژول سنسور تشخیص فرمالدئید ( Formaldehyde ) مناسب برای کاربردهای الکتروشیمی
Principle Introduction:
ZE08-CH2O is a general-purpose and miniaturization electrochemical formaldehyde detection module. It utilizes electrochemical principle to detect CH2O in air which makes the module with high selectivity and stability. It is built-in temperature sensor to make temperature compensation. It has the digital output and analog voltage output at the same time. It is a combination of mature electrochemical detection principle and sophisticated circuit design.
Applications :
Portable detector, air-quality monitor, air cleaner, air renewal system, air conditioner, smart home &etc.
