Product Information

SO2-A4 Sulfur Dioxide Sensor SO2 Sensor Description

Alphasense Sulfur Dioxide gas sensors operate using proven fuel cell technology.

 

SO2-A4 Sulfur Dioxide Sensor size:

20mm diameter, the industry standard size for portable gas detectors

 

The SO2 range provides OEMs with reliable sensors for use in a variety of applications. Strong signal levels combined with low zero current allows resolution below 1ppm and an operating range for safety applications up to 2,000ppm. The sensors are designed for use in both fixed site and portable instrumentation.

 

The SO2 sensors offer our electrolyte leak-free guarantee and reliable long-term detection performance. The leakproof housing is moulded with a colour coded top for ease of identificatio
