Overview
The NGP40-CLO2 portable chlorine dioxide detector adopts DPD photometry and photoelectric Colorimetric detection principle, which replaces traditional visual Colorimetry, eliminates human error, and has high measurement resolution. The instrument is suitable for water plants, industrial and mining enterprises, and domestic or industrial water inspection departments to control the concentration of chlorine dioxide in water to meet the specified water quality standards.
Features
1. Small and beautiful appearance, simple operation, stable and maintenance-free operation, capable of long-term reliable operation.
2. Equipped with large-screen LCD display, clear digital display, low drift, High Accuracy circuit system.
3. Adopt high-intensity long-life light source, no need to replace, preheat for 30 seconds to work normally.
4. Using DPD Colorimetry assay, randomly equipped with rapid assay reagents.
Principle
The instrument adopts DPD spectrophotometry and photoelectric Colorimetric detection principle. During the measurement, chlorine dioxide in the water reacts with DPD reagent to make the water sample turn pink. The water sample is placed in the photoelectric Colorimetric seat of the instrument, and the concentration value of chlorine dioxide is obtained by comparing the depth of Color.
Applications
Water works, industrial and mining enterprises, domestic water inspection, industrial water inspection
Standards
GBT 5750.11-2006 drinking water standard inspection method
Steps
1. Add DPD reagent to the water sample to cause it to react pink.
2. Put the reacted water sample into the photoelectric Colorimetric seat of the instrument.
3. Color depth is automatically compared and chlorine dioxide concentration is displayed.
Notice
• Please make sure the instrument is preheated for 30 seconds before making measurements.
• Please check the battery power before use to ensure that the power supply (6F22 9V battery) is sufficient.
• When measuring, the operation steps should be strictly followed to ensure the accuracy of measurement.
• Reagents should be properly stored to avoid contamination or failure.
• The instrument should be stored in a drying and clean environment to avoid violent vibration.
