Nitrate testers with colour touch display
Coloured sensory
— coloured screens equipped with sensors and allowing you to control the device by touching the display — similar to how it happens with smartphones.Such a display is even more expensive than a simple coloured display, but this is offset by ease of operation: the touch screen can display a wide variety of controls, it is more visual and intuitive than hardware panels with buttons, wheels and other mechanical elements. In addition, the number of such elements can be reduced to an absolute minimum, which allows you to give the device a neat appearance and slightly increase its reliability. Because of this, touch screens are quite popular nowadays.
