概述：
余氯仪适用于大、中、小型水厂及工矿企业、游泳池等地的生活或工业用水的余氯浓度检测，以便控制水的余氯达到规定的水质标准。
测仪原理：
本仪表应用微电脑光电子比色检测原理取代传统的目视比色法。消除了人为误差，因此测量分辨率大大提高。
summary:
the residual chlorine meter is suitable for detecting the residual chlorine concentration of domestic or industrial water in large, medium and small water plants, industrial and mining enterprises, swimming pools, etc., so as to control the residual chlorine of water to meet the specified water quality standard.
principle of measurer:
the instrument uses the principle of photoelectron colorimetry to replace the traditional visual colorimetry. the artificial error is eliminated, so the measurement resolution is greatly improved.
technical indicators:
1. measurement range: 0-5mg/l
2. power supply voltage: 220v
3. resolution: 0.01mg/l
4. repeatability: 1%
linear error: ± (5% fs 1 word)
