QB2000 SO2 alarm controller is consisted of alarm controller and gas detector etc; it can work together with various gas detector, is easy to fix; it realized the detection for 8, 16 or 32 physical quantity, displaying, and public alarm control. When the detected gas density in the air reaches or exceeds the preset value, the controller will give out audio-visual alarm immediately to remind you take safety precautions and start exhaust, control and start exhaust or other peripheral devices to avoid explosion, fire, toxicosis to protect the safety of life and treasures. This system applies to metallurgy, petrol, petrifaction, chemistry, light industry, coking, municipal administration, gas, pharmaceutical, sewage dealing and many other special industry and field that need proofing for fire, explosion, and toxic gas leakage.
Characteristics:
◆high-performance sensor
◆ 128*64 dot matrix big screen liquid digital display
