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)
