Over the last two decades, the measurement of pH has grown dramatically. This parameter has come out of the lab and is being monitored in areas such as the environment, food, agriculture, horticulture, wastewater, pharmaceutical, cosmetic industry, aquaculture, metal finishing and education.
Hanna has now redesigned their popular waterproof series to better fit your hand and allow you to change the default values and set the parameters to your application. Other new breakthroughs include Intelligent Electrodes & Meters, where the meter will prompt for recalibration only if necessary.
