Programmable meters with multicolour bargraph indicators NA6 type are destined to measure and recording d.c. current or d.c. voltage, temperature, resistance and other non-electrical magnitudes like: level, flow, pressure, humidity. NA6 type is vertical with 2-measuring channelsand with 2 bargraphs and 2 displays.
Meters with bargraph are devices ensuring both a high measurement accuracy and very well visualization of the measuring process courses. Very well visualization 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 industrial fields, e.g.food industry, pumping stations and savage-treatment plants, chemical industry, weather stations, brewing industry and many other fields where they are destined for visualisation of the measured value and evaluation of the monitored manufacturing process change trend. They can also find application in automation systems where programmable controllers are applied.
