This is Electrochemical sensor for Sulfur dioxide (Electrochemical Sulfur dioxide sensor,SO2 sensor).
Many different detection range are available such as:0~1ppm,0~10ppm,0~100ppm,0~1000ppm,0~10000ppm etc.more detais please see below.
Special detection range can be customized.
The Sulfur dioxide sensor Modules are available too.
Size: ready stock for all 4 series. 7 series are produced according to orders.
SCIENOC's Sulfur dioxide sensor is very stable in normal circumstance for more than 6 months, and can detect SO2 with excellent accuracy and fast response speed without reduction of sensitivity.standard warranty is 18 months from dispatch time.extended warranty sensors can be customized.
SCIENOC's Electrochemical SO2 sensor can be retrofitted easily to existing product designs.
