Product introduction:
The hand-held helium gas detector is used in occasions for rapid detection of helium gas concentration, temperature and humidity measurement, and over-standard alarm. The hand-held gas detector uses a 2.5-inch high-definition color screen to display the concentration in real time, and selects gas sensors of famous brands in the current industry. The main detection principles include: electrochemistry, infrared, catalytic combustion, thermal conductivity, and PID photoion. With advanced circuit design and mature kernel algorithm processing, it can detect the gas concentration in pipelines or confined spaces, and the atmosphere environment, and can also detect the purity of various gas leaks and various high-concentration single gases with various background gases as nitrogen or oxygen, and the detection types exceed more than 500 kinds.
