## Description

Product DescriptionA digital hydroponic testing meter for measuring water’s acidity, alkalinity, electrical conductivity (EC), total dissolved solids (TDS), temperature, and salinity (salt content) to help optimize its quality for gardening and water treatment applications. The highly responsive sensor probe utilizes a lithium glass membrane to instantly determine pH readings with highly precise ±0.01 accuracy. This all-in-one pH pen tester for water features an IP-67 rating, specially sealed to withstand moisture and heat, as well as block out intrusive dust and sand. For further protection, the hydroponic pH meter is built with a sensor shield to safeguard your probe in between uses. The included 4.00 pH, 7.00 pH, 12.88 mS, and 1413 µS calibration solutions ensure consistently accurate measurements, while the 3M KCL solution supports proper storage conditions to help extend the lifespan of the pH and PPM meter.Replaceable ProbeEach pH monitor sensor probe can be effortlessly replaced to support ongoing accuracy and speed with every reading. This extends your digital meter’s lifespan while simultaneously increasing savings by eliminating the need to purchase new lab pH meters. Simply install a replacement probe and continue monitoring your water quality without interruption.ApplicationsThis fast-acting nutrient test alkalinity meter to help you determine how well your water uptakes nutrients. Fit for use as a pH meter for plants in horticultural settings like gardens, grow tents, greenhouses, and hydroponics systems. In addition, its application spans far beyond plant growing, capable of being a general pH level tester for water used in swimming pools, spas, aquarium fish tanks, and beverage homebrewing applications to help determine water safety.
