Dialed right in! Works great good value

Quick and accurate

Used for indoor hydroponic gardening. The Hanna is great built quality and accuracy. A little pricey, but worth the money. I was going through cheap "imported" meters every month or two months due to cheap quality. . Been using a Hanna for almost a year old now and it still works perfectly.

Unit is well thought out. Calibration is easy. Hold calibration for about 2 weeks. Very easy to maintain. Real asset for monitoring my aquarium.
