Application Notes
-
Soldering for pins are prohibited during installation;
-
Pins are prohibited from being broken and bent; Electrolyte leakage may cause damage, please do not disassemble the sensor at will;
-
To avoid contact with organic solvents (including silica gel and other adhesives), paints, chemicals, fuel oils and high concentrations of gases;
-
All electrochemical sensors can’t be completely encapsulated with resin material, nor can they be immersed in an oxygen-free environment, otherwise the performance of the sensor may be damaged;
-
All electrochemical sensors should not be used in environments containing corrosive gases, which can damage the sensor;
-
When testing and applying the sensor, please avoid vertical front air intake;
-
The intake surface of the sensor shall not be blocked or contaminated;
-
The waterproof and breathable membrane above the sensor is forbidden to be uncovered or damaged;
-
The sensor should not be subjected to excessive impact or vibration;
-
Do not use the sensors if the casing is damaged or deformed;
-
It is slow to return to the initial state after long-term use in a high concentration gas environment;
-
The working electrode and the reference electrode should be in an open state when the sensor is stored;
-
It is forbidden to package the sensor with hot melt adhesive or sealant with curing temperature above 80 °C;
-
It is forbidden to store and use the sensors in high concentration acid gas for long time.
