Application Notes

Tin soldering is prohibited.
Before using, power on to aging for more than 48 hours is necessary.
Don’t disassemble the sensor to avoid the damage caused by electrolyte leakage.
Avoid contacting organic solvent (including Silicone rubber and other adhesive), coatings, medicine, oil and high concentration gases.
All the electrochemical sensors shall not be encapsulated completely by resin materials, and shall not immerse in non-oxygen environment, otherwise, it will damage the function of sensor
All electrochemical sensors shall not be applied in corrosive gas environment, or the sensor will be damaged
Zero calibration should be finished in clean air.
During test and usage, sensors should avoid the gas inflow vertically
The side for inflow can’t be choked and polluted.
The laminating film above the sensor surface can’t be uncovered and damage.
Excessive impact or vibration should be avoided
It takes some time for the sensor to return to normal state after it is applied in high concentration gas
Working electrode and reference electrode of the sensor shall be in short circuit when stored
Prohibit to use the hot cement or sealant of which the curing temperature is higher than 80 to make the capsulation for the sensor.
Prohibit storage and usage for long time in alkaline gases with high concentration.
Do not use the sensor when the shell is damaged
