HI-98129 :thumbsup:

order the 7 and 4 ph calibration solutions with it, way more acurate with dual-point calibration IME!

Alsbeth,
I agree the 98129 and with the calibrating solutions. Watch for a deal coming up (from your's truly)......

I have the hanna duel (watercheck) conductivity/ph meter .. :thumbsdown: It's not working after 1 year. It also never kept the calibration and had to be recalibrated weekly.
puchased the calibration solution and storage solutions in the pint bottles cheaper and you might need the extra solution.
IMO I would try someother meter...
