Installation Instructions

Notice
1. The gas to be measured needs to be pretreated to ensure that the oxygen at the sensor inlet is free of dust, water and oil;
2. The air outlet of the sensor should be connected with the outside atmosphere to ensure the safety of emission without blockage;
3. Do not smoke or use open fire near the sensor;
4. Ensure the integrity of the pipeline in use to avoid gas leakage;
5. Do not disassemble or assemble the sensor by yourself without professional or manufacturer's permission, otherwise the sensor will be damaged and the manufacturer will not guarantee it Or maintenance services;
6. Please read the instructions carefully before use to avoid personal injury or sensor damage. Installation Requires
1. Correct installation sequence of oxygen concentration sensor: air tank - flow regulating device - oxygen concentration sensor - check valve - humidification cup
2. Working environment of oxygen concentration sensor: 5 ~ 55 ºC, operating under normal pressure
3. It is recommended to install one-way valve at the outlet of oxygen concentration sensor to prevent the compressor from recoil and damaging the ultrasonic probe
4. The oxygen concentration sensor should be installed away from the compressor and electromagnetic interference
