sulfur dioxide alarm
The main function of sulfur dioxide alarm is to detect the concentration of sulfur dioxide gas, and then when the concentration reaches the set alarm concentration, the equipment will give an audible and visual alarm to remind people present. Achieve safe operation or production. The alarm decibel can reach more than 70 decibels.
Sulfur dioxide alarm is a kind of sulfur dioxide detector with acousto-optic alarm function, which is mainly modified from fixed sulfur dioxide gas detector. Its function is to give people a safety reminder in time when sulfur dioxide gas reaches the alarm point through the sound and light alarm work, so as to avoid the damage and loss of people's lives and property as much as possible. The fixed sulfur dioxide detector has the function of sulfur dioxide alarm. For example, it can also convert the concentration of sulfur dioxide gas monitored on site into various standard signals, and then integrate them into the system host. The detector of sulfur dioxide alarm is also a fully intelligent gas detector designed with the most advanced imported VLSI technology, international standard intelligent technology level design technology and proprietary digital-analog mixed communication technology. Other parameters of the sulfur dioxide alarm are the same as those of the fixed sulfur dioxide detector, so you can refer to the above.
