PPM-800 formaldehyde analyzer
Formaldehyde analyzerAccording to the national standard GB50325-2010 for indoor air quality, a unique three-level sensor is used, with a highly sensitive electrode electrochemical formaldehyde sensor as the detection unit, to detect the very low volatile formaldehyde 77 in indoor air. When the detected formaldehyde is sucked in by the air pump and comes into contact with the sensor storage chamber and the sensitive electrode of the electrochemical sensor, an electrochemical reaction occurs, which outputs a stable electrical signal. The electrical signal is processed by the central processor and the gas concentration value can be accurately displayed on the LCD screen in numbers. The sensitivity of its detection will be 20-100 times greater than that of diffusive sensors.
It can be widely used in indoor environment formaldehyde detection, environmental decoration, scientific research and teaching, environmental monitoring departments, and specialized equipment for formaldehyde detection in inspection and quarantine.

3、 Product Features
1. The sensitivity of electrochemical sensors is 20-100 times higher than that of diffusive sensors; Can detect lower concentrations of formaldehyde molecules;
2. Electrochemical sensors are unique two electrode sensors that do not require independent reference voltages or battery power supply;
3. Using DC7.2V1800mA high-capacity lithium-ion rechargeable battery, it can measure continuously 50 times;
4. Electrochemical sensors have an ultra long service life of over 5 years;
5. The instrument automatically monitors the capacity of lithium-ion batteries during operation to prevent over discharge of the batteries;
Guidelines for Purchasing Indoor Air Quality TestersWith the widespread use of home decoration, the concentration of indoor pollutants is increasing, affecting people's health. In order to standardize the quality of various materials and protect people's health, the country has introduced a series of indicators to propose restrictions:
