Measuring Chlorine in Industrial Processes

Chlorine is used in a variety of industries, from the chemical and pharmaceutical industries to textile companies. It’s most commonly known for its ability to kill bacteria and clean water supplies. Chlorine can be found all over your local supermarket as it often makes an appearance in everyday items like toilet paper!
Why is it Important to Measure?
To maintain quality chlorine levels, you must often monitor the levels of this chemical using a total residual chlorine sensor. The demand rate refers to the chlorine that is used up when disinfecting for each cycle. To keep up with these demands, residual chlorine can be added on top of that, which will help continue cleaning cycles without interruption.
You need a reliable, accurate way to measure your chlorine levels. A high concentration of chlorine is unnecessary and can end up costing you more money in the long run. Low concentrations mean that bacteria will grow unchecked within your process and affect productivity or efficiency at achieving other goals like disinfection. This is where chlorine residual analyzers come in.
Our 7070iX Residual Chlorine Analyzer is our latest innovation in water treatment testing. The advanced technology allows the detection of residual chlorine and other oxidants down to 1 ppb, making it a valuable tool for all sorts of applications from industrial plants to compliance purposes!
Our new total residual chlorine sensor provides the most accurate measurement possible at this extreme sensitivity level. It’s been designed with an eye towards accuracy because even one ppm (1/1000th) can cause problems, as we’ve seen time and again across industries where chlorine-based solutions are used.
How is Chlorine Measured?
Industrial process engineers need accurate, cost-effective free chlorine residual analyzer systems. Two main types of testers are used to measure chlorine levels in the water, colorimetric and amperometric.
Colorimetric tests are used to determine the pH level of a substance. There are two types: manual and automated. The manual test requires you to use pool testing, but it is inaccurate in real-time process control because it takes time to return results. Automated colorimetry can report on an average reading over long periods, thereby reporting more accurately than its predecessor since one does not need reagents or other equipment that may take up space or require maintenance. However, they’re only EPA approved for reporting purposes.
The second way is via amperometric analyzers. Amperometric analyzers are unlike any other on the market. They feature a rugged chlorine sensor that automatically compensates for pH, and there’s a variety of different models to choose from. So, make sure to visit us for all your total residual chlorine sensor needs.
