Zhengzhou Winsen Electronics Technology Co., Ltd. ME2-CH2O-16×15 Formaldehyde Sensor ME2-CH2O-16×15 electrochemical sensor detect gas concentration by measuring current based on the electrochemical principle, which utilizes the electrochemical oxidation process of target gas on the working electrode inside the electrolytic cell, the current produced in electrochemical reaction of the target gas are in direct proportion with its concentration while following Faraday law, then concentration of the gas could be get by measuring value of current. Features： * Low consumption * High precision * High...

Zhengzhou Winsen Electronics Technology Co., Ltd. There are two ways to fix the ME2-CH2O-16×15 sensor Fix the sensor in PCB or instrument shells through fixing hole by using nut Fix the sensor through the fixing slot Fixing hole Fixing slot Cross interference gas ME2-CH2O-16x15 sensor also responds to other gases besides CH2O. Below are the response characteristics of interferential gases Gas Do not break and bend the PCB terminals; To preheat for no less than 48hs before using; Do not take apart the sensor, otherwise electrolyte leakage can cause sensor damage; Sensor shall avoid organic solvent,...

Zhengzhou Winsen Electronics Technology Co., Ltd. Do not open and damage the above waterproof breathable membrane of the sensor; Excessive impact or vibration should be avoided； Do not use the sensor when the shell is damaged； It takes some time for the sensor to return to normal state after applied in high concentration gas； Working electrode and reference electrode of the sensor shall be in short circuit when stored； Please do not encapsulate the sensor using melt adhesive and sealant, whose curing temperature is higher than 80 ℃; Please do not expose and use the sensor in high concentration...
