Hydroponic Meter PRO Kit, All-in-One pH Pen, Interchangeable Probe

A 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.
