The Apera PH60 already comes with calibration solutions — however, only as a small 50 ml starter quantity. This is enough for two calibrations, after which you will need supplies. This set therefore additionally includes the 250 ml storage bottles: five times the amount per solution.
Included in the Set
- Apera PH60
- Apera pH Calibration Solution 4.01 (250 ml)
- Apera pH Calibration Solution 7.00 (250 ml)
- Apera 3M KCl Electrode Storage Solution (250 ml)
Why order together
If you reorder the solutions individually later, you pay for shipping a second time. In this set, they are shipped right along with the device. Then there is the bundle price: the storage bottles are 15% cheaper here than individually, while the device price remains unchanged. You save €5.56 compared to buying them separately.
Good to Know
If you use your device daily, calibrate about once a month, or at least before important measurement series. A 250 ml bottle is sufficient for about ten calibrations, depending on the vessel size.
