Formaldehyde Rapid Tester

The formaldehyde rapid detector employs an electrochemical sensor. During detection, air passes through the sensor, and formaldehyde molecules undergo redox reactions, generating an electrical current signal. The intensity of the current is proportional to the formaldehyde concentration. It is used for on-site rapid determination of formaldehyde levels in indoor air, furniture, and other materials.
Selection
When selecting, consider that the detection range must cover 0.01–1 mg/m³, with a resolution of at least 0.01 mg/m³ and an error of less than ±5%. Check the sensor lifespan and calibration cycle, pay attention to ease of operation and data storage functionality, and ensure the product has a Pattern Approval Certificate for Measuring Instruments.
