Apera Instruments pH Calibration Buffer Solution Kit (7.00, 4.00) with KCL Storage Soaking Solution for pH and ORP Electrodes

This bundle pairs Apera Instruments pH calibration solutions with their 3M KCL storage solution to keep your pH measurements accurate. The calibration kit contains 8 oz bottles of pH 7 and pH 4 buffer solutions to calibrate your meter before testing. These NIST-traceable buffers are highly accurate to +-0.01 pH. Produced in an ISO facility using strict controls, these solutions ensure you get reliable pH measurements. The 3M KCL storage solution extends the life of your pH and ORP electrodes. Electrodes lose sensitivity when stored dry over time. By soaking them in this solution, you can restore performance. The storage solution is also handy for conditioning electrodes and keeping them ready for use. With high-purity chemicals and color-coded bottles for easy identification, Apera’s calibration and storage solutions work hand in hand. Use the calibration kit to standardize your meter and probes before testing. Then rely on the storage solution to maintain electrode sensitivity between uses. This bundled pair gives you the tools to keep your pH testing reliable.
