Select the world's leading sequential injection platform, reagent consumption is less, for the conventional chemical method instrument reagent dosage of 120, suitable for long-term online monitoring;

Highly integrated multi-channel directional valve, a single valve body can achieve 8 flow path switching function simple structure;

The valve head flow path adopts laser microengraving technology to precisely control the size and positioning of the groove to ensure that the flow path has no dead volume when the valve position is switched, so as to ensure that there is no reagent residue;

Innovative liquid storage ring structure, samples or reagents are not directly in contact with the syringe, avoiding the wear and corrosion of the injection flow path;

The analysis method is consistent with the national standard, which is suitable for automatic monitoring of hexavalent chromium concentration in surface water of environmental pollution source discharge.

High resolution injection pump, the minimum quantitative volume is 0.8uL, the sample and reagent volume quantitative accuracy, good repeatability, much higher than the conventional chemical method instrument;

Automatic chroma and turbidity compensation algorithm, fully considering the actual situation of the site water sample, the monitoring results are real and reliable;

Specially customized pretreatment sampler for hexavalent chromium monitoring allows suspended particles to be sampled at the same time, and then crushed by homogenizer, which is filtered by coarse and fine, multi-stage, combined with automatic backblowing and automatic cleaning, to ensure good representative samples and avoid large suspended particles clogging pipelines;

The unique bubble stirring mixing technology ensures that the sample and reagent are fully mixed.
