Detailed information on RH-8519 wall mounted phosgene (COCL2) detection alarm:

RH-8519 wall mounted phosgene (COCL2) detection alarmProduct Overview:
The RH-8519 series single point wall mounted phosgene detection alarm is an instrument that can continuously detect the concentration of phosgene in the working environment. It can be widely used in various on-site environments such as factories, offices, and warehouses to monitor the concentration of phosgene online. This phosgene detection alarm adopts a natural diffusion gas detection method, and the sensitive element adopts an imported electrochemical sensor from Membrapor, Switzerland, which has high sensitivity and excellent repeatability; High brightness LED backlight and LCD display screen display the concentration value of leaked gas in real time. If it exceeds the preset alarm point, the sound and light alarm signal and relay control signal will be immediately activated; The international standard 4-20mA signal can be directly connected to the factory DCS system, and the RS485 digital signal can be connected to the factory upper computer.
