Formaldehyde (CH2O) fixed gas detector - B12
B12 series CH2O fixed gas detector is a 2-wire transmitter designed to accurately detect formaldehyde – also known as formol or methanal. Highly resistant to corrosion and humid environments, B12 formaldehyde detector is available with or without local display. Detailed description
Formaldehyde, formol or methanal (CH2O) detection
Formaldehyde – as well as benzene and carbon dioxide – is the purpose of a very strict regulation regarding 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.
