Q & A’s

The Chemtrac Chlorine Residual Analyzer is an advanced instrument designed to measure the concentration of free chlorine or total chlorine in water systems, ensuring water safety and quality.

The analyzer uses a colorimetric method where a reagent reacts with chlorine in the water sample, producing a color change. The intensity of the color is then measured to determine the chlorine concentration.

The analyzer is suitable for a wide range of applications, including drinking water treatment plants, wastewater treatment facilities, industrial process water, and cooling towers.

The measurement range varies depending on the model but typically covers from 0 to 5 mg/L for free chlorine and 0 to 10 mg/L for total chlorine.

Yes, the Chemtrac Chlorine Residual Analyzer is capable of measuring both free chlorine and total chlorine in the water.

Regular maintenance includes cleaning the sensor, replacing reagents, and calibrating the instrument. Detailed maintenance schedules and procedures are provided in the user manual.

Yes, the analyzer is designed for easy installation and comes with comprehensive instructions. Most users can install it without the need for professional assistance.

Yes, the Chemtrac Chlorine Residual Analyzer can be integrated with SCADA systems for remote monitoring and data management.
