1、 Product Introduction

1. Product principle

Residual chlorine is divided into free residual chlorine and compound residual chlorine. Free residual chlorine: generally refers to chlorine molecules, hypochlorous acid molecules, and hypochlorous acid ions in water. Compound residual chlorine: generally refers to the compound formed by the combination of chlorine with free ammonia or organic amines in water. The sum of two types of residual chlorine is called total residual chlorine.

This instrument applies the principle of microcomputer photoelectron colorimetric detection to replace the traditional visual colorimetric method. Eliminating human error, the measurement resolution is greatly improved.

2. Product Usage

The JC-YL-1AZ portable residual chlorine detector is suitable for detecting residual chlorine concentration in domestic or industrial water used by large, medium, and small water plants, industrial and mining enterprises, swimming pools, and other places, in order to control the residual chlorine in water to meet the specified water quality standards.
