SW721PLUS is a multi-gas sensor integrating SF6 and O2. SF6 uses the NDIR infrared absorption detection principle,and O2 uses the electrochemical principle.
The infrared detection module uses a patented optical cavity,imported light source and dual-channel detector to achieve dual optical path reference compensation in space. It has good selectivity,no oxygen dependence,life,and low power consumption; it has a built-in temperature sensor for temperature compensation.
SW721PLUS uses 485 output.
