How to use a hydrometer to measure the density of electrolyte
If suddenly the battery of your car does not work properly, and the electrolyte level is within normal limits, first of all it is necessary to measure its density. And for this, every motorist should know how to use a hydrometer.
What is a hydrometer and how it works
Areometers are of various types: it all depends on the density of what fluid needs to be measured. The most practical value for the average motorist has an automobile hydrometer designed to measure the density of both the electrolyte and the cooling liquid. It can be purchased at any store selling auto parts, or on the market.
Observe safety measures
When measuring the electrolyte density, it is important not only to know how to use the hydrometer, but also to observe safety measures. All work should be carried out in protective gloves, glasses, appropriate clothing and shoes. Do not allow electrolyte to enter the body and eyes. All actions with batteries must be carried out in a warm ventilated room, because during the charging process, toxic gas is released.
If acid gets into the eyes or on the skin, the area of the chemical burn should be rinsed abundantly with water. In no case should you try to neutralize the acid that has fallen on the body (for example, soda). This will only exacerbate the situation. Then it is necessary as soon as possible to apply to a medical institution.
When working with antifreeze, it is also necessary to comply with safety measures. The radiator cap can only be opened after the coolant has completely cooled down, so that it does not eject and, as a result, get burned.
After measuring the density, the hydrometer must be thoroughly rinsed in running water before the final removal of acid residues or coolant. If this condition is met, the hydrometer for measuring the density of the electrolyte (antifreeze) will serve you more than a dozen years.
