Formaldehyde, formol or methanal (CH2O) detection

Formaldehydeas well as benzene and carbon dioxide – is the purpose of a very strict regulation regargind allowed concentrations in public access buildings (PAB). This colorless gas features a suffocating smell, is soluble into water and has been classified since 2015 as a proven carcinogenic agent.

Particularly well-suited for detecting formaldehyde (CH2O) – also known as formol or methanal - B12 fixed gas detecor features a 4-20 mA linear ouput with more or less 5% accuracy and an optional digital display. Its enclosure is made of polystyrene, making this fixed gas detector waterproof and corrosion-resistant.
