SO2-B4 Electrochemical Sulfur Dioxide Gas Sensor For Air Quality Monitoring Flue Gas Analysis

Technical Features:

High - precision Detection: Using proven fuel cell technology, with strong signal levels and low zero current, the resolution can reach < 10 ppb, which can meet the requirements of high - precision detection in air quality networks.
Good Linearity: The linearity error is 0 - 2 ppb at 100 ppm SO2, and it is linear in the range of 0 - 10 ppm SO2, which can ensure the accuracy of measurement results.
Reliable Performance: The sensor provides an electrolyte leak - free guarantee and reliable long - term detection performance. The leak - proof housing is molded with a color - coded top for easy identification.

Application Scenarios:

It is suitable for fixed - installation sensing heads, portable safety instruments, urban/indoor air monitoring and stack gas analyzers, etc., and can provide reliable data support for air quality monitoring and industrial emission detection.
