This is Electrochemical sensor for Formaldehyde.(Electrochemical Formaldehyde sensor).
Normal detection range: 0~5ppm,0~10ppm,0~20ppm,0~30ppm,0~50ppm,
0~100ppm,0~1000ppm,0~5000ppm,0~20000ppm
Special detection range can be customized.
The Formaldehyde sensor Modules are available too.
Size: ready stock for all 4 series. 7 series are produced according to orders.
SCIENOC's Formaldehyde sensor is very stable in normal circumstance for more than 6 months, and can detect Formaldehyde 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 Formaldehyde sensor can be retrofitted easily to existing product designs.
