Toxic gas alarm detector and harmful gas online monitoring systemThis product adopts an industrial 128 * 64 dot matrix LCD screen, which has the characteristics of high stability, high accuracy, and high intelligence. It has a rich variety of external control ports, and users can freely choose the type and access port of the transmitter to be attached. Through simple settings, on-site detection and alarm can be carried out. The system has integrated sound and light alarms and provided a relay normally open control terminal.

The gas online monitoring system is widely used in situations where toxic and harmful gases need to be detected. When the indicator of a certain gas to be detected on site is out of or below the set standard, the system will perform a series of alarm actions, such as alarm, exhaust, trip, etc.

Detection principle: Collect standard 4-20mA signal input or RS485 communication input (optional), analyze and process the current gas concentration of each channel, and operate relevant alarm signals. The information can also be transmitted to the computer through the RS485 bus.

Applicable objects: The system supports input signals for various standard detectors, such as gas detectors for carbon monoxide, hydrogen sulfide, sulfur dioxide, hydrogen, ammonia, oxygen, chlorine, and combustible gases.
