The Swiss company MAAG, founded in 1910, is a well-known manufacturer of gears, special equipment for their production and special tools for their control.
Today, MAAG is an international holding company for the production of gears and special equipment, located in many countries around the world on several continents.
The production and control of gears is a very difficult technical task, because the requirements for the complex profile of the gears are very strict, the gears themselves have a large range of sizes.
The main controlled parameter of gears is their module, which is controlled by pedometers with variable measuring inserts.
Features of rare pedometers "MAAG" are the following:
The measurement range of the "junior" pedometer (head №3750) is 1… 4 modules;
The range of the "older" pedometer (head №4043) is equal to 2… 4 modules;
The body of the "older" pedometer is made of massive polished steel casting;
The body of the "younger" pedometer is made of ebonite (thermosetting plastic, which was quite common in Western Europe before World War II, in the USSR ebonite was very common until 1970);
Both pedometers have sturdy wooden cases with secure latches.
