Suitable for large, medium and small water plants and industrial and mining enterprises, living or
industrial water chlorine concentration detected in order to control the water, chlorine achieve
water quality standards.
Principle:
Using the DPD method, using micro-photonics colorimetric detection principle to replace the
traditional visual colorimetry.
Eliminating human error, the measurement resolution is greatly improved. When measuring, when
the measured water into the reagent water sample will turn red. Then this water into the
photoelectric colorimeter seat, instrument by comparing red shades resulting in the concentration
of Residual chlorine size.
Features:
1. Microcomputer, keyboard easy to use.
2. Automatic zero adjustment, 1 to 5 automatic calibration.
3. AC-DC dual-use, high-performance lithium battery, charging 2 hours can offer 4 hours of
continuous use
4. Using the unique semiconductor light emitting device (patent application No. 99226785.2), its
light source life is about tens of thousands of hours, much longer than incandescent lamps (about
350 hours).
5. High resolution. Up 0.01mg / L.
