Free Chlorine Analyzer

Free chlorine analyzer has proven to be an extremely popular instrument with many hundreds of monitors in operation in Canada today. The AMI Trides provides state-of-the-art three-electrode sensor technology, exceptionally long chlorine sensor life, sensor self-cleaning, and requires only simple maintenance. Uses no consumables. Stable readings, with very low zero drift and fast response. Other Disinfectants: Equally capable of measuring for ozone, chlorine dioxide, bromine and iodine and can also also be used for swimming pool water. From the smallest…

Chlorine Monitoring System

Chlorine monitoring system, provides monitoring for several species of disinfectants with one instrument. The instrument can monitor for free chlorine and total chlorine, and can also calculate monochloramine, combined chlorine and disinfection byproducts (THM, HAA, etc.) as a group. Supplied as a complete wall-mounted unit, the AMI Codes-II CC is ideal for monochloramination treatment, monitoring and control, breakpoint chlorination control, and is also used for wastewater effluents and pool water quality monitoring. In addition to monitoring for these parameters, the…

Simply hold the DPD dispenser over sample and press the button to conveniently dispense the correct volume of reagent. Designed for zero contact use, where your fingers do not come into contact with the reagent, and…

How is free chlorine measured?

There are two basic methods for measuring Free Chlorine in water; Colorimetric analysis and Amperometric analysis.

Colorimetric measurement can be further divided between a simple test strip method and a more accurate Photometer/Colorimeter measurement using free chlorine instrumentation. A Photometer/Colorimeter measurement is achieved with the addition of a DPD reagent in a given sample size, and using an optical instrument to read the results. A deeper colour indicates the presence of more Chlorine and the chlorine instrument can determine the relationship between the colour intensity and corresponding chlorine conscentration.

Amperometric analysis consists of a sensor which returns a voltage value, interpreted as concentration. The most accurate free chlorine instrumentation includes both temperature and pH measurement.

The Swan Trides Amperometric free chlorine analyzer includes every vital measurement in a compact, reliable and extremely accurate instrument. Consisting of two platinum electrodes and a reference electrode with a liquid junction for accurate measurement. The electrode has an extremely long service life. The design is innovative with a built in flow detector and continuous sensor cleaning. Integrated pH measurement for the automatic calculation of Free Chlorine at changing pH levels. The pH sensor is also located in a flow chamber where at no flow conditions it remains wet.
