Its real strength lies in its color-changing display , which allows you to see at a glance if the reverse osmosis water is properly purified. When the display turns green , the measurement is below 25 ppm. When it turns red , it indicates that the water is not pure enough and that the filtration system needs to be checked. Allows you to check the actual quality of the reverse osmosis water in a few seconds. Very practical color display for immediate and unhesitating reading. It also measures dissolved solids and temperature with a single device.
