GfG Instrumentation 2901-09-008 IR 29E Methane Transmitter, Display

GfG Instrumentation, 2901-09-008, IR 29E Methane Transmitter, Display, 4-20mA

Unlike traditional LEL sensors, IR 29 transmitters do not need the presence of oxygen to detect gas. Since they are not affected by sensor poisons they don’t require periodic adjustment to make up for lost sensitivity. The IR 29 continuously monitors its functions for proper performance, and can even identify and communicate required service procedures.
