Digital Bargraphs

Meters with bargraph are devices ensuring both a high measurement accuracy and very well visualisation of of the measuring process courses. Very well visualisation of the process is possible through using in meters 3 and 7-coloured bargraph  built with diodes made in the gallium nitride technology. They can find application in various fields, e.g. food industry, pumping stations and savage-treatment plants, chemical industry, weather stations, brewing industry and many other monitored manufacturing process change trend. They can also find applications in automation systems where programmable controllers are applied.
