pH/EC Calibr. Set pH 4,01/ 7,00/ 10,01 + (84/ 1413/ 12880) µS + 3M KCl + Calbox

This set contains three bottles of pH calibration solution (pH 4.01 / pH 7.00 / pH 10.01), three bottles of EC calibration solution (84 µS / 1413 µS / 12.88 mS) and one bottle of 3M KCl storage solution, each bottle containing 250ml. In addition, a Calbox is included, which can be filled with up to four different solutions and makes calibration much easier. pH solutions: pH 4.01, pH 7.00 and pH 10.01, 250ml each EC solutions: 84 µS/cm, 1413 µS/cm and 12.88 mS/cm (=12880 µS/cm), 250ml each. Storage solution: 3M KCl solution, 250ml Precise pH calibration: The pH solutions accuracy of pH 0.015 allows highly accurate calibration Easy recognition: Based on the colors, you can recognize the correct pH solution at a glance (pH 4: red, pH 7: green, pH 10: blue) The EC calibration solutions are suitable for any type of conductivity meter The 3M KCl storage solution preserves the sensitivity and accuracy of the pH/ORP electrodes Use immediately: Instead of dissolving powder in distilled water first, you can use the solutions immediately Long shelf life, batch certificates available on the Internet The Calbox has space for 4 solutions and caps that can be closed, simplifying each calibration more
