Overview
This manual describes the 61-1001RK-05 hydrogen 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 hydrogen detector.
The 61-1001RK-05 hydrogen detector includes the NC-6205-05 hydrogen detector and a
junction box. This manual may also be used for the NC-6205-05 hydrogen detector which
