Hanna Instruments hi-73127 vervangende pH-elektrode

Bewährt

Arrived and sat around for 90 days before installing in my pH probe. So simple, read 7.01 pH with my calibration solution which matched my expectation.

Great product worked good for both of my hanna instruments HI98127 ph meters.N8ce to be able to replace the probe rather than the whole unit.My first HI98127 is about 4 years old and the other is atleast 10 still going strong with new batteries and electrode

Wasn't dry when I got it.

Good price and quality for replacement part that extends the life of our digital pH tester/ thermometer. Easy to replace.
