1、 Product Features

Ø The determination of hexavalent chromium was developed according to GB7467-87, and the measurement data is accurate and effective.

Ø Adopting a high brightness, long-life cold light source with excellent optical performance, the light source has a lifespan of up to 100000 hours.

Ø Large screen LCD display in Chinese, sampling and adding reagents for measurement, simple and time-saving operation.

Ø Can save 20 standard curves and 999 measured values (date, time, parameters, test data).

Ø The memory standard working curve, and users can also calibrate the curve as needed.

Ø It has data power-off protection function and data storage function.

2、 Detection principle

Determination of hexavalent chromium: The chromogenic reagent reacts directly with hexavalent chromium to form a purple red complex, and its absorbance is measured by spectrophotometry. After processing and calculation by a microcomputer chip, the hexavalent chromium content (mg/L) is directly displayed.
