Product Description

The controller has an LCD display, which is not affected by external light. Controller LCD display, not affected by external light, Chinese display of gas name and concentration value, sound and light alarm when the concentration exceeds the standard. It is easy to operate with the internationalized icon indication and Chinese instructions.

The controller is characterized by good stability, high accuracy, and intelligent setting of parameters. With abundant external control ports, users can freely choose the type of sensors to be connected and the access ports and can carry out on-site detection and alarm through simple settings. When the index of a gas to be detected does not meet the set standard, the system will automatically carry out a series of alarm actions, such as sound and light alarm, air exhaust, tripping, etc. (depending on the user’s use scenario). Hangwei Sensors are Best Fire Protection LCD Screen Manufacturer.

The controller has the advantages of fast response time, high reliability, low failure rate, easy maintenance, etc. It can be widely used in petroleum, chemical, liquefied gas, coal, pharmaceutical, metallurgy, municipal and other industries, and is the ideal choice for updating and replacing gas alarms.
