Overview
This manual describes the 61-1000RK-05 combustible gas detector (internal amplifier
type). This manual also describes how to install, start up, maintain, and calibrate the
detector when it is used with a gas monitoring controller. A parts list at the end of this
manual lists replacement parts and accessories for the combustible gas detector.
The 61-1000RK-05 combustible gas detector includes the 61-0140RK-05 combustible gas
