Calibration Powder
	Buffer solution powders are an extremely popular way of buying pH buffer solution. They are very portable, making them ideal for use in any outdoor testing application, each sachet is sealed until open, thus ensuring the solution is fresh and gives an accurate calibration. Another benefit is a long shelf life, making them ideal for infrequent users who may not need to calibrate their meter very often. All our buffer solutions are manufactured to established formulas and are standardised with a pH meter that is calibrated to a traceable primary standard buffer solution.
