6. Things to note
From the condensation state to the non-condensation state, the system can return to normal working state within 2 hours.
Please try to avoid vibration. If vibration, drop, and welding time is long, the sensor measurement accuracy may be made.
Got worse.If serious vibration or drop occurs, the accuracy of the product needs to be verified.
Do not use it for a long time in environments with high dust density.
Avoid in containing HF，H2S，SO2，HCL,NOX，NH3,PH3,CL2，F2, O3，H2O2 It is used for long-term use in an environment with acidic, alkaline and strong oxidizing gases.
Avoid exerting external forces in any direction on the housing, which can affect sensor performance and may cause damage
