Hanna Instruments

Hanna Instruments are globally recognised specialists in precision measurement, with over 40 years of experience developing reliable tools for pH, EC, and water testing. Founded in Italy in the late 1970s, the brand supports growers who want accurate readings, better control over feeding, and confidence that their water and nutrient solutions remain consistent throughout the grow cycle.

Rather than guesswork, Hanna Instruments focuses on practical, grower-ready measurement. Products such as the GroLine pH Tester provide fast, accurate readings tailored to nutrient solutions, while the GroLine Combo pH/EC/Temperature Tester allows multiple key parameters to be monitored at once. Built for durability and ease of use, these tools help growers spot issues early, fine-tune feeds, and maintain stable conditions season after season.

For growers who value accuracy, consistency, and tools they can rely on long term, Hanna Instruments from Greens Horticulture offers well-priced measurement equipment that is in stock now and ready to support precise feeding and more dependable results.
