buffer solutionFor super accurate calibration use these solutions at 25 degrees centigrade and never keep an opened solution for more than 2 months.
As well we offer pH electrode storage/refill & cleaning solutions.
These are necessary for pH and EC Meter and any expensive pH/EC instruments requiring more care and attention.
