Overview
This manual describes the 61-1001RK 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 hydrogen detector includes the NC-6205-01 hydrogen detector and a
