MR-AX multi-gas detector uses high-sensitivity electrochemical, photoion, infrared, catalytic combustion and other intelligent sensors. Applying intelligent processing platform and digital sensor technology, we have realized detection technology that resists cross-interference of multiple gases (independent intellectual property rights). In terms of external functions, the detector has functions such as graphic display and remote platform monitoring. It can optionally upload detection data simultaneously, view data in real time on the mobile APP, alarm data, send text messages and other functions. It also uses a 4-wire high-precision resistive touch screen for operation. Personnel can easily view and maintain data on site. MR-AX can be used online and in portable mode. It has a built-in lithium battery and can be used continuously for 8 to 16 hours in the event of a power outage.
