Ambient diffusion gas detector equipped with toxic and oxygen-sensitive sensor
Gas detector with dedicated gas detection principle, providing excellent selectivity and minimal interference
from other gases by reacting specifically to the target gas
Internal pressure explosion-proof
Calibration and program setting ZERO point, Span ( Automatic Setting with no Volume except for 4~20mA)
Calibration and maintenance by one person
Minimization of the impact of noise - temperature/humidity
Connection of the analog standard output(4~20mA) signal to DCS & PLC monitoring system
Install the system in hazardous areas at industrial sites to measure combustible gases in real-time, and
provide 4~20mA standard output and connect to control devices, alarm devices, and monitoring systems
