Function description:
1) No manual calculation is required, just take about 50ml of liquid sample and read the density (specific gravity) and concentration values of the sample directly with one click.
2) Equipped with fully automatic zero point tracking and the ability to remove skin and weight throughout the entire process;
3) Standard blocks (ordinary weights/stainless steel/PTFE anti acid and alkali weights) can be selected according to different liquids;
4) It has the function of setting the upper and lower limits of specific gravity. When the measured specific gravity value exceeds the set value, the display screen will prompt HI, otherwise it will prompt LO, which can help determine whether the specific gravity of the measured liquid is qualified;
5) Compensation function for errors caused by air buoyancy;
6) Digital display for direct reading of specific gravity and concentration values;
7) Equipped with a standard RS-232 interface, it can connect to printers and computers to output test data;
8) Suitable for use on production lines/laboratories.
