35-3010RK-03 Sample-Draw Detector • 1

Overview

This manual describes the 35-3010RK-03 sample draw detector. This manual also 
describes how to install, start up, maintain, and calibrate the sample draw 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 detector.

Specifications

Table 1 lists specifications for the 35-3010RK-03.

WARNING: When using the 35-3010RK-03, you must follow the instructions and
