"Made in the USA"

This set requires a very small quantity of electrolyte to secure a
reading because it is scientifically designed.

Float has a specific gravity scale range of 1.100 to 1.300.
Precisely calibrated; all floats re-tested are guaranteed to be accurate.

This scientifically shaped barrel is proportioned to give free and
accurate readings continually. The true inside diameters are to
.005 inches. This finely produced piece has a one ounce rubber bulb
capacity. We use only the very highest grade acid-resistant rubber with
a durable rubber ended tip. The set is a convenient 12 inches.

Customer's name printed in float on orders of 200 or more.

To secure an absolutely correct specific gravity reading of the electrolyte
in a battery, the temperature of the electrolyte must be taken into
consideration since the reading changes with the temperature.

This instrument is designed to give you the temperature reading and also
a gravity correction for the temperature indicated.

The thermometer has a scale range of 0-130 degrees Farenheit graduated
in single degree division, numbered every ten degrees. It also has
a specific gravity correction scale in red giving the corrections
for the temperature of the electrolyte.
