2pcs Suction Type Battery Electrolytic Hydrometer Electro-hydraulic Density Meter

Description It is generally difficult to grasp the concentration ratio of the electric water in the battery during the preparation process, so a measuring tool should be used. This measuring tool is a density meter. Usually the density of electrolyte preparation is controlled at about 1.27. Features - Color: Assorted color.- Size: 29.00X5.50X5.50cm/11.40X2.16X2.16 inch.- Material: Glass.- Measuring range: 1.1-1.3.- Battery hydrometer is used for determining the specific gravity of battery acid.- When in use, the meter should be immersed vertically in a transparent container, and the electro-hydraulic density can be read from the meter at any time.- Made of high-quality material for a long time and durable use.- It has a simple design, but very practical in use, giving you a good using experience.- The hydrometer It is easy to use, bring much convenience to you.Packing list: 2 x hydrometers
