Electrochemical Formaldehyde Detector

The electrochemical formaldehyde detector generates an electric current through the redox reaction between the electrolyte inside the sensor and formaldehyde, with the current intensity being proportional to the formaldehyde concentration. It is used for rapid detection of formaldehyde concentration in indoor air, furniture, and building materials, with the test results displayed directly as numerical values.
Selection
When making a selection, focus on the sensor's lifespan and anti-interference capability, check the calibration cycle and method of the instrument, verify that the detection range covers the required concentrations, ensure the response time and recovery time meet the usage scenario, and confirm that the product has a calibration certificate issued by a legally authorized metrology institution.
