HI701 residual chlorine (free chlorine) Colorimeter is an instrument used to measure the concentration of free chlorine (Cl2) in water samples. Free chlorine usually refers to chlorine (Cl2) that exists in a free state in water. It is a common disinfectant that is often used in water treatment and swimming pool disinfection. The HI701 residual chlorine (free chlorine) Colorimeter is based on the chemical reaction between free chlorine and a certain reagent to produce dyes or compounds whose concentration is proportional to the content of free chlorine in the water sample. The concentration of free chlorine in a water sample is determined by measuring the optical density, or color, of the stain.
Able to measure free chlorine in a lower concentration range with higher sensitivity.
It can complete the measurement in a short time and is suitable for applications requiring fast feedback.
With high precision and accuracy, it can provide reliable measurement results.
It is widely used in drinking water treatment, swimming pool management, industrial production and other fields to ensure water quality safety and product quality.
No complicated operating steps are required, and it is suitable for laboratory and field testing.
