Cautions!



Tin soldering is prohibited.



Before using, power on to aging for more than 48 hours is necessary.



Pins can’t be broke off or bent.



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 pure 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
