Introduction
Section 1 Introduction
1.1 System Description
See Appendix C on page 161 for a
list of abbreviations, acronyms, and
definitions used in this manual.
This manual applies only to Cat. No. H-4195; –X010; –X020; –X030; –X040;
–X050; –X060; –X070; –X080 and H-6195– analyzers and describes the
installation and operation of the analyzer, shown in
Figure 1 on page 16 . The
analyzer measures organic carbon in liquid samples ranging from 0.015 mg/L
to 20,000 mg/L. In the analysis process, carbon is converted to
carbon dioxide, which is then measured with an IR detector. The analyzer
uses the EPA approved UV-persulfate oxidation method, which produces the
most reliable TOC measurement. The analyzer meets customer specifications
worldwide, and complies with ISO, EPA, EN, DIN, CE, UL, CSA, FM,
and NAMUR regulations.
Software navigation is simplified by the use of dialog prompts for single
sample analysis, analyzer validation, and analyzer calibration.
The analyzer is capable of local 4–20 mA, optional RS232 CSV data logging,
and ModBUS communication.
The analyzer is designed to facilitate customer maintenance. All key
components are located for easy access. All connection ports are located on
the outside of the analyzer. A dual-stream option is available.
Sample dilution can be added to the standard instrument. The optional
dilution configuration is shown in illustrations throughout this manual.
1.2 Applications
The analyzer can measure either Total Carbon (TC) or Total Organic Carbon
(TOC) in water continuously or from grab samples. It is recommended for use
in the following applications:
• Boiler feed water
• Bulk chemical
• Pharmaceutical process water
• Condensate and cooling water
• Unit out fall
• Industrial wastewater
• Industrial effluents
1.3 Major Components
There are two enclosures—one for liquids and one for electronics.
The enclosures are available in epoxy powder coated steel or stainless steel.
The top electronics enclosure is separate and sealed from the bottom liquids
enclosure. Refer to
Figure 1 .
