Ch2o(formaldehyde) is a kind of gas which will cause damage to human body. It exists in many products like chemicals, laminate flooring, particle board, household products, glues, permanent press fabrics, paper product coatings, fiberboard, and plywood. It is also widely used as an industrial fungicide, germicide and disinfectant. Jw-100 ch2o detector adopt with high performance electrochemical sensors and sophistic- Ated circuit design, it has features like high stability, excellent anti interference ability. When the indoor ch2o concentration is over the standard, this detector can provide site alarm and remote alarm according to different degrees of ch2o (connect with alarm host).
High-risk security situations do not leave any margin for error thus requiring intricate security procedures designed to ensure safety and piece of mind. The tm-915 has been created specifically with this in mind. Tm-915 mainly used in detecting the close state of door and window, when the door or window opened as unknown reason and the detector will send out specific radio wave to alarm host to achieve remote alarm.
