Featuring ±0.01 pH accuracy and an interchangeable lithium glass membrane probe, it measures pH, electrical conductivity (EC), total dissolved solids (TDS), temperature, and salinity. Built tough with an IP67 rating, it withstands moisture, dust, and heat, making it ideal for hydroponics, aquariums, pools, and more. The kit includes calibration solutions and a sensor shield, ensuring long-lasting accuracy and reliability for millennial professionals who demand precision and durability in their water testing tools. ## 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. Review: ALL in 1 Hydroponic Meter - Been using this meter for about 1 year now and one of the best all in 1 meters. Really helped to dial in my grows. Insures my EC, PH, salts, and ppms are all at the desired readings. Review: Goodbye BluLab pens - So long blue labs... been using this for a while now.

Hopefully i don't need to buy another soon, but i may when the time comes. Easy calibration and the blue backlight is Hella bright! ## Features - Hydroponic pH reader for water quality assessment to help monitor and maintain proper solution levels. - Measures acidity, alkalinity, EC, TDS, temp, and salinity of water for gardens, aquariums, pools, and more. - Replaceable sensor probe with sensitive glass membrane delivers instant pH readings with pinpoint accuracy. - IP-67 rated to be sealed from high-volume moisture, dust, and sand; can also withstand high levels of heat. - Includes KCL, 4.00 & 7.00 solutions with 12.88 mS & 1413 µS solutions for lab-grade precision. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CLQWNSMP | | Best Sellers Rank | #20,539 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #24 in Lab pH Meters | | Brand Name | AC Infinity | | Customer Reviews | 4.5 4.5 out of 5 stars (106) | | Included Components | Hydroponic Meter, Replaceable Probe, Calibration Solutions | | Manufacturer | AC Infinity | | UPC | 819137024212 | ## Product Details - **Brand:** AC Infinity - **Manufacturer:** AC Infinity - **UPC:** 819137024212 ## Images ![Hydroponic Meter PRO Kit, High Precision Digital pH Pen with ±0.01 pH Accuracy and Interchangeable Probe, All-in-One Temp Salinity EC TDS pH Meter, Water Hydroponic Gardens Aquariums Pools - Image 1](https://m.media-amazon.com/images/I/614MbH-cNlL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ ALL in 1 Hydroponic Meter *by O***L on October 29, 2025* Been using this meter for about 1 year now and one of the best all in 1 meters.
