Introduction of gas tester
Gas tester is a kind of instrument and instrument tool for gas leakage concentration detection, mainly refers to portable/hand-held gas tester. The gas tester is mainly used. The gas sensor is used to detect the type of gas in the environment. The gas sensor is used to detect the composition and content of gas. It is generally believed that the definition of gas sensor is based on the classification of the detection target. That is to say, all sensors used to detect the composition and concentration of gas are called gas sensors, regardless of whether they use physical methods or chemical methods. For example, sensors for detecting gas flow are not considered as gas sensors, but thermal conductivity gas analyzers are important gas sensors, although they sometimes use roughly the same detection principle.

Main performance:

1. Measure oxygen, carbon dioxide, humidity and temperature.
    A. Determination of oxygen content. The advanced oxygen sensor of British City Company is adopted.
    B. Carbon dioxide content. Infrared carbon dioxide sensor from Vaisala, Finland is adopted.
    C. Humidity measurement. This machine integrates two humidity measurement functions, one is located at the beginning of the air inlet, and the other is handheld (optional). Adopt the products of Humirel, France.
    D. Temperature measurement. (Optional) The platinum resistance temperature sensor imported from Germany is packaged as a probe to measure the internal temperature of fruits and vegetables.
2. Adopt portable design, integrated with maintenance-free battery and air pump, convenient for on-site work.
3. The LCD screen is used for display, with intuitive display content and generous appearance.  
4. It is equipped with a micro printer to print sample data.
5. It can save 250 sample data.
6. It can be connected with the computer to upload data to the computer for long-term storage.
7. It can alarm for battery power loss and operation error.
