Tips: Common Types of Formaldehyde Detection
Common formaldehyde test instrument in the market can be broadly divided into the following categories:
1. One of the CH2O gas detector uses the probe for testing. It is characterized by direct reading of data and easy to carry.
2. Another test instrument is the use of spectrophotometry to analyze the reading. This kind of instrument has a more prominent characteristic - high accuracy, has little interference from other gases, and has temperature and humidity compensation.
3. Portable formaldehyde gas detector is an instrument that can continuously measure formaldehyde. This product is suitable for environment monitoring, industrial production, chemical industry and other places with formaldehyde.
4. Handheld HCHO monitor can be zero calibrated on the site under test without the help of outdoor air. It is applied to the detection of formaldehyde gas in public places, civil buildings and building materials.
