Features:
1. The electro-hydraulic density meter is used to measure the density of battery electro-hydraulic. 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.
2. It is generally difficult to grasp the concentration ratio of the electric water in the battery during the preparation process, so it is necessary to use a test.
3. Measuring tool, this measuring tool is a density meter. Usually the density of electrolyte preparation is controlled at about 1.27.

Specifications:
Measure range: 1.10-1.30
Whole length: about 330mm/13 inch
High precision: 0.005
Quantity: 1 PC
Measuring range: 1.10-1.30
Purpose: used to determine the solution in acid or alkaline storage batteries.
Assemble before use.
(1) Install the red rubber pad with holes on it, mainly to prevent the density meter from being sucked into the gasbag.
(2) Then install the density meter into the glass tube.
(3) Put the tip on again.
(4) Install the gasbag and it can be used.

Packing List:
1 x Battery Hydrometer

Note:
1. It is not easy to master the concentration ratio of water in battery, so the densitometer is very important.
2. Usually the density of the electrolyte should be controlled at 1.27.
