S Transmitter • 5

Overview

This manual describes the 65-2330RKSS hydrogen sulfide (H

2

S) transmitter. This manual 

also describes how to install, start up, maintain, and calibrate the transmitter when using it 
with a gas monitoring controller. A parts list at the end of this manual lists replacement parts 
and accessories for the H

2

S transmitter. See the controller operator’s manual for information 

specific to the controller.
