Brief introduction of TP-X4 portable combustible gas detection and alarm instrument :
TP-X4 portable combustible gas detection and alarm instrument is used for portable and rapid detection of combustible gas concentration, temperature and humidity measurement and exceeding the standard alarm. TP-X4 composite four-in-one gas detector uses a 2.31-inch high-definition color screen to display the concentration in real time , and uses well-known brand gas sensors. The main detection principles are: electrochemical , infrared, catalytic combustion, thermal conductivity, and PID photoion. With advanced circuit design and mature core algorithm processing, it has obtained a number of software patents and appearance patents. TP-X4 can detect the gas concentration in pipelines or confined spaces and atmospheric environments. It can detect gas leakage or the purity of a single gas with a high concentration of nitrogen or oxygen as the background gas. It can detect more than 500 types of gases .
