overview

This instrument is widely used for the determination of surface water, groundwater, wastewater, etc.

This instrument is developed using imported methods, using imported high brightness and long-life cold light sources as the light source. The colorimetric tube is used for color comparison, and the operation is simple and time-saving. It is paired with a large LCD Chinese display for direct data reading; The instrument comes with a standard curve and can also calibrate the curve as needed; Comes with measurement value storage function and printing (date, time, parameters, test data); The instrument has data power-off protection and data storage functions to prevent data loss due to errors.

Measurement principle

Zinc can react with colorants in a certain environment to form stable complexes, and its absorbance can be measured by spectrophotometry. After processing and calculation by a microcomputer system, the actual zinc content (mg/L) can be directly determined.
