Photoelectric Photometric Formaldehyde Detector

The instrument measures the change in absorbance of the solution after the reaction between formaldehyde and phenol reagent using a photoelectric sensor, converting the optical signal into an electrical signal to calculate the formaldehyde concentration. It is used for rapid on-site detection of formaldehyde levels in indoor air, furniture, etc., offering simple operation and intuitive results.
Selection
When selecting, pay attention to whether the detection range covers common standard values. Sensor lifespan and calibration cycles affect usage costs. The adaptability to environmental temperature and humidity determines measurement stability. The device must have a calibration certificate issued by a legally authorized metrology institution.
