AQ-2019 Fixed Combustible Gas Detector, 3 to 100%
Technical features：
The AQ-2019 combustible gas detection alarm is a functional and practical gas detection terminal. The alarm shell is designed as an explosion-proof shell and can be used in hazardous areas in explosion-proof environments.
There is an LED indicator light on the front of the equipment to indicate the current equipment status and display the value of combustible gas detected by the sensor, making it easy for users to directly adjust the alarm on site.
The product can communicate via 4~20mA, active/passive switching output, or standard RS485; it also supports wireless 4G communication to send data to the platform. It uses local Bluetooth to configure parameters and firmware upgrades for the device. It can also Parameter configuration and firmware upgrade of the device through remote platform.
Applications :
- Pipe Gallery Gas Transmission and Distribution
- metallurgy, refining
- Petrochemical
- School
- Biochemical medicine
