2.0 Overview
The CLX-Ex2 Online Chlorine Monitor allows for the reading of chlorine
levels of process water on-line. The CLX-Ex2 has been designed
to meet the design criteria specified by Standard Methods for the
Examination of Water and Wastewater (21th Edition) Method 4500-Cl
G. DPD Colorimetric Method. The CLX-Ex2 uses a 515nm LED as the
measurement light source.
This instrument has been designed to operate in explosive atmospheres
and meets the IECEx rating as stated in the specifications. The instrument
does this with the use of an approved purge/pressurization controller
called the Air Sentinel. Please refer to the companion manual Cat. No.
28749 for all information on:
• Operation of the Air Sentinel.
• Electrical power connections.
• Purge Air Connection.
