ZE07A-CH2O electrochemical formaldehyde module
ZE07A-CH2O electrochemical formaldehyde module is a general-purpose and miniaturized module. Using the electrochemical principle to detect CH2O in the air has good selectivity and stability. Built-in temperature sensor for temperature compensation; at the same time, it has digital output and PWM output, which is convenient to use. ZE07A-CH2O is a general-purpose gas module designed and manufactured by closely combining mature electrochemical detection technology with sophisticated circuit design.
