Calibration sets

Complete sets 60 ml

Five bottles of 60 ml: two pH values, ORP 475 mV, KCl storage solution and cleaning solution.

• Set pH 4 / pH 7 / 475 mV — for dosing systems that calibrate acid and neutral.
• Set pH 7 / pH 10 / 475 mV — for systems that calibrate neutral and alkaline.

Sets in sachets of 20 ml

Fresh buffer solution in sachets of 20 ml. One sachet, one calibration — do not reuse or pour back.

• pH 4 and pH 7 — sachet 20 ml (2×10)
• pH 7 and pH 10 — sachet 20 ml (2×10)
• pH 4, pH 7 and 475 mV — sachet 20 ml (3×10)
• pH 7, pH 10 and 475 mV — sachet 20 ml (3×10)

Which calibration set do you choose?

Choose the set with the pH values that the manual of your meter or dosing system requires: pH 4 and pH 7, or pH 7 and pH 10. If you also calibrate an ORP probe, take a set with ORP 475 mV: most swimming pool controllers ask for 475 mV. The sets with sachets contain 10 sachets per value; in a complete pack each solution comes in a bottle of 60 ml.

How to use the set

Open the sachet and place the probe directly in it; the probe also fits in the 60 ml bottle. Pour KCl storage solution and cleaning solution into a separate beaker; let the probe soak in it.
