Overview
DGB-423 Portable Multi-Parameter Water Quality Analyzer is a LEICI brand photoelectric Colorimetry Water Quality Analyzer. It adopts LED testing technology, integrates LED Illuminant with specific absorption peak wavelength, has built-in standard Linear dispersion, and directly uses Colorimetric tube as measurement container. Compact size, easy to operate and carry. The instrument can measure ammonia nitrogen parameters and supports extended custom Miscellaneous project parameters. It is suitable for on-site measurement or laboratory analysis of surface water, industrial wastewater, landscape water for sewage regeneration, drinking water, swimming pool water and other water quality.

Principle
The DGB-423 Water Quality Analyzer uses photoelectric Colorimetry to illuminate the sample with an LED Illuminant of a specific absorption peak wavelength to quantitatively analyze water quality parameters by measuring changes in light absorption. Built-in standard Linear dispersion directly uses a Colorimetric tube as a measurement vessel for fast and accurate measurement.
Applications
Surface water, industrial wastewater, wastewater recycling landscape water, drinking water, swimming pool water
Standards
GLP specification
Steps
1. Prepare samples and use Colorimetric tubes as measurement containers
2. Turn on the instrument and select Measurement parameters
3. Colorimetric tube into instrument measurement slot
4. The instrument automatically measures and locks the result, and directly reads the Measured value
5. Store, review, or print data as needed
Notice
• Make sure the instrument is fully charged or connected to a power supply before use
• Colorimetric tube specifications need to be 16mm outer diameter * 100mm length, capacity 10ml
• Avoid direct light during measurement to ensure stable signal
• Regularly calibrated to ensure Measurement accuracy
• Pay attention to the automatic shutdown time setting to reduce power consumption
• Data storage and deletion follow GLP specifications
