Handheld Formaldehyde Gas Tester

The handheld formaldehyde gas detector utilizes an electrochemical sensor, where formaldehyde molecules undergo redox reactions at the electrodes during detection, generating current signals that are converted into concentration readings via circuitry. It is used for on-site rapid measurement of formaldehyde emissions from indoor air, furniture, and other sources, with a detection range of 0–10 ppm and a resolution of 0.01 ppm.
Selection
When selecting, focus on the sensor type, as electrochemical sensors are suitable for routine detection. Check the detection range and accuracy; the common range is 0-5 ppm with an accuracy of ±5%. Pay attention to the calibration cycle and method, ensuring it has automatic temperature and humidity compensation. Consider the response time and data storage capability, with a typical response time of <60 seconds. Confirm that the product complies with the GB/T 18204.2 standard.
