Mroace Digital Water Quality TDS Meter

Features

• 4-IN-1 MULTIFUNCTION WATER QUALITY TESTER: Archer Life Hall TDS Meter accurately measures TDS (Total Dissolved Solids), EC (Electrical Conductivity), and Temperature (°F & °C) in one device. Ideal for drinking water, tap water, well water, hydroponics, aquariums, pools, spas, laboratories and more.
• LARGE BACKLIT LCD WITH SMART COLOR INDICATOR: Equipped with a large, easy-to-read backlit LCD screen, this device provides clear visibility from wide angles and in low-light or nighttime conditions. The intelligent color indicator automatically changes the backlight based on water quality: a green backlight (≤40 ppm) indicates the water is safe for direct drinking, while a red backlight (>40 ppm) serves as an alert that the water is not suitable for drinking.
  (Based on international TDS reference standard of 40 ppm as dividing line.)
