Chinese Online Phosphate Analyzer DC-890Main Features
Uses precision metering pumps for automatic dosing instead of traditional peristaltic pumps.
Precision metering pumps ensure accurate reagent dosing.
Employs long-life, high-stability, and highly reliable imported light sources and receiving components.
The flow path combines vortex and siphon principles with a pinch-type water path switching mechanism, fundamentally eliminating measurement interference caused by alternating channel measurements and completely eliminating cross-contamination issues.
Designed with a specialized cuvette to completely eliminate bubble interference.
To ensure accurate sample water addition, a fixed sample cup is integrated into the flow path, measuring the sample water each time.
An optimized mixing chamber design utilizes air vortex principles for stirring, achieving optimal chemical reaction assistance.
Automatic calibration of samples during each measurement, effectively avoiding measurement deviations due to sample background or related factors.
Online flow sampling without interruption, automatic sample interruption alarm, and automatic channel switching when no sample is present.
