pH Meters for Water, Soil & Hydroponics
pH Meters for Plant Growing
pH meters allow growers to quickly measure the acidity or alkalinity of water, nutrient solutions and growing media. Maintaining the correct pH helps plants access nutrients efficiently and is particularly important in hydroponics, coco and controlled plant cultivation.
Digital pH Meters for Water and Nutrient Solutions
Choose from compact pH pen testers, professional handheld meters and multi-parameter devices measuring pH together with EC, TDS or temperature. For larger hydroponic systems, continuous pH monitors and controllers provide ongoing measurement of nutrient solution parameters.
Soil and Substrate pH Meters
For direct measurements in growing media, choose soil and substrate pH meters equipped with suitable probes. These meters are useful for checking conditions in soil, coco and other substrates.

Choosing the Right pH Meter
For occasional measurements, a compact digital pH meter is usually sufficient. For frequent testing, consider a professional meter with automatic temperature compensation and a replaceable electrode. Larger hydroponic systems can benefit from continuous pH monitors and controllers that monitor the nutrient solution directly in the tank.
For complete nutrient solution monitoring, you may also need an EC meter to measure electrical conductivity. When measuring directly in growing media, explore our soil and substrate meters. Regular use of pH calibration and storage solutions helps maintain meter accuracy and keeps electrodes in good condition.
