Caution
To avoid possible serious cuts from broken glass, wear rubber gloves
and use extreme care in assembling the hydrometer syringe. If the
hydrometer has previously been used and may possibly contain some
electrolyte clinging to the wall, use goggles in assembly operations to
protect the eyes.
Note
To avoid electrolyte contamination, hydrometers used in lead-calcium
or lead-antimony cells should not be used in the Round Cell.
Assembling the Hydrometer
Step Action
1
Remove any mold seam flash from the rubber parts that fit
against the glass barrel.
2
Wrap several thicknesses of heavy cloth around the glass
barrel to protect the hands.
3
Use water to wet the rubber parts and the glass barrel before
assembly operations.
4
Fit the rubber parts to the glass barrel.
Flexible Tube Length Determination
Step Action
1
Fit the flexible tube supplied in the hydrometer kit on the end
of the Z-shaped hard rubber tube.
2
Cut off the end of the flexible extension so that it extends a
minimum of 1/2 inch below the low-level line.
