Page 9: Method Of Analysis
General information Figure 1 Chlorine analyzer 2.2.2 Method of analysis Free available chlorine (hypochlorous acid and hypochlorite ions) oxidizes the DPD indicator reagent at a pH between 6.3 and 6.6 to form a magenta-colored compound. The depth or intensity of the resulting color is proportional to the concentration of chlorine in the sample. -
Page 10: Theory Of Operation
General information 2.2.3 Theory of operation The analyzer is designed to capture and analyze a portion of the sample every 2.5 minutes. The sample portion is captured in the colorimeter measuring cell where the blank absorbance is measured. Measurement of sample blank absorbance allows compensation for any turbidity or natural color in the sample, and provides an automatic zero reference point. -

Page 20: Optional Air Purge
Installation Optional air purge Air purge may be necessary if the analyzer is located in an environment with high humidity and/or caustic vapors. The goal is to maintain a slight positive pressure in the instrument with dry instrument air. The air purge connection is located on the left side of the instrument enclosure. To connect an air supply, remove the plug in the quick connect fitting then connect ¼-inch poly tubing by pushing the tubing into the fitting. -

Installation 3.8.1 Power connections DANGER Electrocution hazard. Only qualified personnel should conduct the tasks described in this section of the manual. Connect equipment in accordance with national, state and local electrical codes. Power connections are made at the terminal strip located in the left side of the electrical compartment and are accessible when the customer access cover is opened. -
Page 22: Wiring The Instrument
Installation Additionally, electrical and instrumentation standards require a local means of removing power from the product. The instrument is supplied with a power on/off switch that is located inside the instrument enclosure. To remove relay power from the instrument, an external customer-supplied 5A fused switch or a 5A breaker is required. -
