Calibration Solution pH and EC

4.01 pH PH 7.01 buffer solution. One of the most widely used buffer solutions, it is extremely stable and represents the mid-point in the acidic range of the pH scale, particularly those where the pH is expected to be acidic. With which you can keep them in perfect condition and drastically increase their durability and effectiveness.
Calibrate your meter, regardless of brand

The superior quality pH 4.01 PH 7.01 technical buffers are supplied with a Certificate of Analysis traceable to the National Institute of Standards and Technology (NIST).

Milesimal buffers have a higher resolution (0.001) for more accurate pH measurements.

How to use:

You should clean the meters with a toothbrush moistened with distilled water and remove all adhering debris.
You can use a cleaning solution specific to the brand of your meter.
In the case of PH meters: you should prepare the 4.0 and 7.0 solution, and calibrate your meter first low and then high.
In the case of EC meters: you must prepare the calibrating liquid and calibrate the device.

In the drop-down menu at the top right of the page you can select different types of calibration liquids, which are usually used specifically with the meters of the same brand.
