In the course of the centuries the most recognizable category of weights used were ‘traditional’ beam balances. The introduction of electricity reformed the weighing industry. Since the 19th century many new types of weights (based on electricity) have come into view. Some of the examples of electricity-powered balances used nowadays are:
As the name suggests, they are most frequently encountered in numerous industries (transport, trade and agriculture, warehouses etc.) where they are used to weight objects up to several hundred tones. Resistance to decay, extreme temperatures, humidity and acid makes them the most damage proof scales in the world.
Recent technological inventions have enabled us to measure not only the weight of a person but also their BMI (Body Mass Index) as well as the percent of the body fat. Maximum load found in most personal balances ranges around 150 KG.
Usually settled on the ground, they are used to weigh the front axle load. The driver steers the car which runs on the scale.
Most frequently used in medical and jewelry businesses, they are used to assess the weight of extremely small, sometimes microscopic-like, objects with accuracy up to 1 nanogram. Only electronic weights can reach that level of precision.
Those who like to cook and follow different recipes use kitchen scales to measure the weight of e.g. flour or grits.
