Description
AC Infinity Hydroponic Meter PRO Kit, pH & EC Meter
This digital hydroponic tester measures pH, electrical conductivity (EC), total dissolved solids (TDS), temperature, and salinity to help you optimize water quality in grow and water applications. The responsive probe with a lithium glass membrane delivers instant, highly accurate pH readings (±0.01). With an IP67 rating, the device is sealed against moisture and dust for reliable use in demanding environments. Included calibration solutions (pH 4.00 & 7.00, plus 12.88 mS & 1413 µS) help ensure consistently precise measurements, while the KCL solution supports proper probe storage to extend probe and meter life.
Replaceable probe
The sensor probe can be replaced easily when needed, helping maintain long-term accuracy and fast response. This extends the life of your meter and keeps your monitoring uninterrupted.
Applications
Ideal for grow tents, greenhouses, and hydroponic systems to keep nutrient solutions stable. Also works as a water tester for aquariums, pools, spas, and other use cases where accurate water readings matter.
