The utility model belongs to the field of sewage treatment, in particular to a calibration device for a full-automatic anion surfactant analyzer.

Background technique

The automatic anionic surfactant analyzer is a special instrument for analyzing and detecting the content of anionic surfactant in industrial wastewater and environmental water. This instrument is used in environmental monitoring stations and environmental testing institutions at all levels. The standard solution for calibration can be configured and set according to the actual surfactant content range of the user's water sample according to the principle of proximity, because the water samples that the user wants to monitor are generally limited to a certain range. By configuring the standard solution that is close to the user's actual water sample content according to the principle of proximity to calibrate the instrument, the accuracy of the measurement can be adjusted;

At present, the automatic anionic surfactant analyzer itself automatically prepares the standard sample, automatically makes the working curve, and the high-concentration sample can be automatically diluted.
