2in1 water quality tester: Measures pH and EC (conductivity) with a range of 0.00 to 14.00 pH and 0 to 19.99 ms/cm, providing two essential water quality metrics in a single instrument. Auto Temperature Compensation ATC: Includes automatic temperature compensation for accurate readings across varying temperatures. Compact and easy to use, it can be wallmounted or hung for flexible installation. Features plantsafe green LEDs and a backlit display for clear readings in any lighting. Replaceable pH electrode: Uses a BNCtype pH electrode that is detachable and replaceable. You do not need to the entire monitor when the electrode ages, allowing simple and costeffective maintenance over time. Dual display with backlight: Large, clear dual measurement display with backlight for easy reading during longterm or continuous monitoring, even in dim environments. Key benefits Accurate, combined water quality assessment with pH and EC in one device. Maintains measurement accuracy with ATC, reducing misreadings caused by temperature variation. Low maintenance and lower ongoing costs through replaceable pH electrode. Flexible installation options (wall mount or hanging) to suit different setups. Readability in any lighting thanks to the backlit dual display and plantsafe green indicators. Specifications at a glance pH range: 0.00–14.00 pH EC range: 0–19.99 ms/cm Electrode: BNCtype pH electrode, replaceable Display: Dual measurement display with backlight Temperature compensation: Auto Temperature Compensation (ATC) Mounting: Wallmountable or hanging Applications and use scenarios Home hydroponics and garden systems: Monitor nutrient solution quality to maintain pH and EC for leafy greens, herbs, or other crops. Greenhouse irrigation and nutrient solutions: Install on a wall or stand to continuously track water quality for precise nutrient delivery and plant health. Aquaculture and freshwater tanks: Regularly check pH and conductivity in recirculating systems to protect fish and maintain stable water conditions.
