About Diametral

The company was founded in the Czech Republic in 1991.
From the beginning, the company was engaged in the development and production of electronics.
The first product was a car alarm.
This was followed by a micro soldering iron and the first laboratory DC power supply.
Other products were AC laboratory power supplies, isolation transformers and autotransformers.
From these products was only a step towards the first laboratory tables VarioLab.
In 2006, the tables were upgraded to VarioLab +
In 2010, a table for the practical teaching of electrical engineering with the VarioClick mark was established.
In 2013, other tables marked VertiGO for research and development and VariWork for electrical production.
A special group is formed by Uno Volta educational panels focused on vocational education. These panels first entered schools in 2015.
The company is constantly working on new projects and challenges.
