CHARACTERISTICS

According to HJ 488‐ Improved research and development in 2009, with accurate and effective measurement data.

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

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

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

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

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

2、 Detection principle

Fluorine ions react with fluoride reagents and lanthanum nitrate in an acetate buffer medium with a pH of 4.1 to form a blue ternary complex, which is then compared by colorimetric method. After calculation by a microcomputer chip, the fluoride content (calculated as F -) is directly displayed.
