Nitrate testers with monochrome display
Monochrome
— single colour display — usually black and white, with dark icons on a light background (or glowing on a dark one). Such displays are noticeably cheaper than colour displays and consume less power, but they have more modest functionality, are not as convenient and are not well suited for advanced functions. Therefore, this option is mainly used in devices synchronized via Bluetooth (see "Functions"): the main control is carried out through the screen of a smartphone/tablet in them, and its own monochrome display plays an auxiliary role.| monochrome | clear | Save List |
