Traditional buffer calibration solutions are packed in 220ml leak-proof bottles and are recommended for lab application.

Milwaukee sachets are sealed against light and air and are ideal for on-the-spot calibration. Simply open, insert the tester or electrode into the sachet and calibrate. Sachets are sold in boxes of 25 pieces.

Conductivity calibration solutions are used to confirm and adjust the accuracy of meters and electrodes in agricultural, industrial, or scientific environments. A calibration solution is used to calibrate instrumentation for accuracy in aquaculture, hydroponics, waste water treatment, and for scientific applications. It is necessary to use a calibration solution similar in dissolved solids content to the solution to be tested in order to get acceptable accuracies. Calibration solution should be at the same temperature as the test solution to minimize temperature effect errors. Conductivity is the ability of a material or solution to conduct an electrical current. Milwaukee Instruments manufactures electrochemical instrumentation and solutions for water analysis under the Milwaukee and Martini brands.
