Bromine gas alarm and harmful gas detector in hazardous chemical warehouse

Bromine gas alarm and harmful gas detector in hazardous chemical warehouse

The special security bus type combustible/toxic gas alarm host is a fixed wall mounted device that can be equipped with one to multiple channels for continuous and long-term online monitoring of point detectors. The host and detector are connected by bus, making installation and networking convenient. The detector can display independently (on-site digital display) and is equipped with an integrated on-site sound and light alarm light; When the concentration of gas detected in the environment reaches or exceeds the preset alarm value, the alarm immediately emits an audible and visual alarm to remind users to take safety measures and drive the exhaust, cut-off, and sprinkler systems to prevent suffocation and poisoning accidents, thereby ensuring safe production. It can also upload PLC, DCS, fire protection system, and computer upper computer software. This gas alarm controller can be divided into multiple channel quantities: 1-4/1-8/1-16/1-32/1-64/99, etc; Channels 1-4 are suitable for small areas such as restaurant kitchens, paint mixing rooms, small warehouses, etc., and are very economical and practical. Combined with our company's RT series bus gas detector, it forms a gas alarm detection system.
