Ambient conditions
Temperature: -10 to 60°C (14 to 140 °F)
Humidity: 5 to 95%RH
Installation: Pipe-mounted or on panel
Construction: Explosion-proof and Intrinsically safe. (See 1.1.1 “System Components”)
Though the detector construction makes it relatively insensitive to sudden changes in
the gas temperature, extra precision can be achieved by keeping ambient temperature
conditions as constant as possible. In measurements where optimum precision
is required it is therefore not recommended to install the detector in an outdoors
environment, especially not if such installation is prone to direct sunlight.
