ME4-NO2 Nitrogen Dioxide Gas Sensor Profile ME4-NO2 nitrogen dioxide gas sensor is constant potential electrolysis type. Oxidation-reduction reaction with nitrogen dioxide and oxygen take place respectively on the working electrode and on the counter electrode. The process releases electric charge and generates current. The current is in direct proportion to the concentration of nitrogen dioxide. So the concentration of the target gas could be got by measuring the value of current. Features Low power consumption, high precision, high sensitivity, wide linear range, good anti-interference ability,...

Zhengzhou Winsen Electronics Technology Co., Ltd Cross Interference ME2-NO2 sensor also can respond to other gases besides target gas NO2. Following data are the response characteristics of the sensor to interferential gases at certain concentration for your reference. Stable2. Cross interference Interferential Gas 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,...

Zhengzhou Winsen Electronics Technology Co., Ltd 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 Zhengzhou Winsen Electronics Technology...
