Hi all,
I’m new happy owner and user of Hanna PH checker HI-98103.
I’m looking for buying spare 4 and 7 PH calibration solutions. The original Hanna solutions are only being sold in 0.5 litres containers for about £30 per bottle.
I can find cheaper third party solutions and in smaller containers but for some reason they are 4.01 and 7.00 where original are 4.01 and 7.01. Is it important to use 7.01 PH solution or 7.00 PH is equally fine?
Many thanks
Daniel
