As a brand new indoor formaldehyde concentration monitoring instrument, the latest imported electrochemical sensor and high-precision operational amplifying chip are adopted for the formaldehyde tester, which can continuously and directly convert the formaldehyde concentration signal in the air to electric signal in real time and display and reflect the measuring result in LCD digits after microcomputer data processing. It has broken the bottlenecks of the traditional formaldehyde tester that must be operated by the professional and is expensive in detection cost, and it can automatically provide 24-hour continuous real-time monitoring of indoor formaldehyde concentration. The formaldehyde tester can detect indoor formaldehyde gas rapidly, display date, detection time,temperature and humidity data at the detection site. It is featured by simple structure, small volume, ease of carrying and using and visual display. It can widely apply to site quantitative and qualitative detection of formaldehyde in living room, indoor and residential area,public place, living place and factory and workshop. The indoor portable formaldehyde tester is designed and made according to principles in the national standard
GB/T18204.26-2000 Methods forDetermination of Formaldehyde in Air of Public Places.
