PPM400ST formaldehyde detectorThe multi parameter formaldehyde detector produced by PPM company in the UK can directly measure the concentration, temperature, and humidity of formaldehyde in the air. The PPM model is a newly developed compensation function based on the old F400 formaldehyde detector. Even in high humidity conditions, the PPM 400 model can accurately measure low concentrations of formaldehyde, with easy operation and simple calibration.

（1）PPM400ST formaldehyde detectorIt is currently the most advanced formaldehyde analyzer in the world, and our company's model and instrument have temperature and humidity compensation, eliminating the interference of temperature and humidity. A direct reading analyzer specifically designed for detecting low concentration formaldehyde content in fields such as health and epidemic prevention, environmental protection, labor hygiene, and petrochemicals. The instrument adopts a voltage type diffusion electrochemical sensor, which is linearly stable, accurate in results, high in accuracy, strong in anti-interference, has a long service life, and is easy to operate.

（2）Electrochemical sensor (): The formaldehyde analyzer uses advanced electrochemical sensor technology to determine the concentration of formaldehyde in the atmosphere. The sensor consists of two precious metal electrodes and an electrolyte. This analyzer uses high-tech integrated circuits to ensure its reliability.

（3）Serial interface: Through this interface, the analyzer and personal computer can be connected for data acquisition and analysis. It is something that domestic and foreign peers cannot achieve.

（4）Palm style, on-site measurement does not require any other auxiliary reagents, and domestic and foreign similar products cannot compare with it in terms of measurement accuracy and detection limit.
