I. Introduce
Handheld four-gas detector TY-7101D is used in the places where it needs to move quickly to detect the concentration, temperature and humidity of various gases on the site and alarm when they exceed the standard. Handheld four-gas detector TY-7101D uses a 2.5-inch clear color screen to display the concentration in real time. The gas sensor based on the principles of electrochemistry or infrared, catalytic combustion, thermal conductivity, PID photoion, Swiss precision capacitance digital temperature and humidity sensor and the advanced circuit design and mature core algorithm processing of Handheld four-gas detector TY-7101D have been selected and achieved A number of software works and appearance patents.
