About Hanna Instruments
Why Hanna
Hanna makes laboratory-grade meters, and the GroLine range brings that to growers: a continuous monitor that sits in the reservoir and shows pH and EC all the time, so there's nothing to dip and nothing to forget. The solutions keep the probe reading true.
Looking after it
Calibrate with the buffer solutions on schedule, clean the electrode with the cleaning solution when readings drift, and store it wet.
