Temperature curves of CPY20 pH buffers are pre-programmed in all Liquiline series transmitters to simplify sensor calibration and adjustment, reducing your maintenance effort.
The high accuracy and reproducibility of the buffers help you optimize the pH value in your process and to maximize the yield and quality of your product.
CPY20 buffers are available in seven different values from pH 2 to pH 12.
CPY20 pH buffer solutions ensure the reliability and accuracy of your pH measurements.
Field of application
The high-quality CPY20 buffers guarantee pH calibration to ultimate precision. They are produced and bottled in the production laboratory and tested in the calibration laboratory. These tests are performed with a subsample according to ISO 17025 regulations. The buffers are specified with an expanded measurement uncertainty of +/-0.02 pH (> pH 10: +/- 0.05 pH). The buffers contain only FDA-listed preservatives. Using CPY20 you will achieve correct values that you can rely on.
CPY20 pH buffer solutions are used for calibration and adjustment of pH electrodes in all industries. They are optimized for all routine and high precision sensor adjustments in the process as well as in the lab.
The calibration and adjustment can be conducted with:
Memobase Plus CYZ71D software and Memobase Pro
All transmitters of the Liquiline series
All conventional pH transmitters on the market
