AMBU Battery Tester

=FOR AUTO OR RADIO STORAGE BATTERIES A Quick Seller For Your Accessory Department RED, WHITE AND GREEN BALLS TELL SPECIFIC GRAVITY OF BATTERY SOLUTION=

Simplest, most efficient and easiest to read battery tester ever yet offered to the battery owner. Unlike any hydrometer or tester on the market. Instead of the glass float used on ordinary hydrometers, which are hard to read and understand, it has three balls, colored red, white and green which tell the whole story.

Astonishingly simple to test a battery with it, because the following jingle regarding the three balls, and the positions they assume in the electrolyte or liquid tells the story—

“Floats all three, battery is charged fully. Sinks the white, charge still right, Sinks the green, charge is lean, Sinks the red, charge is dead.”

A battery can be tested with it with as much accuracy as any hydrometer on the market. The specific gravity of each ball is accurate to the fourth decimal point. It can be “read” in semi-darkness.

Is only 6½ inches long and designed so that it can be carried in the tool box where it is Always Handy—A mighty big value for only 75c.

Furnished to the Dealer in an attractive counter display box, one dozen to each package. When placed on the counter it sells itself.

AND NOW—

You have been reading how to increase the profits of your shop through the use of materials previously wasted. There is another way of stopping leaks and increasing earnings. That is by making the best possible use of every man's time.

In this connection we would like to tell you briefly about the activities of the Educational Division of the American Bureau of Engineering, Inc.

This institution foresaw the need of providing instruction on fundamental electricity, ignition, starting and lighting and storage batteries, so that garage owners, foremen, general repair men and mechanics could handle electrical repair jobs at a profit.

Here in Chicago we are offering an eight weeks' course of forty-four hours per week, devoted to intensive instruction in theory and practical shop work. This training enables the student to become an expert in this highly specialized field, fitting him to supervise the work of other mechanics or to operate a shop of his own as an expert in Automotive Electrical Repairs.

For those unable to leave their employment and come to Chicago, we have developed a series of Home Study problems and solutions which have proved interesting and practical. Lesson schedules can be arranged to suit the individual student. Close personal cooperation aids the Home Study student in making satisfactory progress.

The two methods of instruction are identical with the exception that the Resident Student gets actual practice in addition to theory.

Through our other activities we are able to keep in close touch with the situation and be certain that the instruction offered is strictly up-to-date and practical.
