7E4-SO2-5 056-0600-200 Electrochemical Hydrogen Cyanide Sensor Is
Used To Measure SO2 Concentration
Features:
Product Description
This product is used to measure the concentration of sulfur dioxide
gas. It adopts a four-electrode structure design and utilizes a
compensation algorithm to enhance the accuracy of low-concentration
gas measurement. This product complies with the performance
requirements stipulated in the 2021 edition of the new CCEP
national standard.
