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 CPY20 pH buffers are available in 2 quality levels.
Certified reference pH buffer solutions: pH values 4, 7, 10. The buffers are produced and bottled in the accredited production area; characterized and checked for homogeneity and stability from bottling to transport and storage in our accredited calibration laboratory according to DIN EN ISO 17025 and DIN EN ISO 17034 regulations. Metrological traceability with an expanded uncertainty of 0.03 pH for pH 4 and 7 and 0.08 pH for pH 10.
Technical pH buffer solutions: pH values 2, 4, 7, 9, 9.2, 10, 12. The buffers are characterized with a typical measurement uncertainty of +/-0.02 pH (> pH 10: +/- 0.05 pH).
CPY20 pH buffer solutions are optimized for all routine and high precision sensor calibrations and adjustments with:
Memobase Plus and Memobase Pro softwares
All transmitters of the Liquiline series
All conventional pH transmitters on the market
Fordeler
All preservatives used in the buffers are FDA-listed for highest product safety in FDA-supervised processes.
The high accuracy and reproducibility of the buffers help you optimize the pH value in your process and maximize the yield and quality of your product.
All offered pH buffers are very robust to meet your high process demands. The certified reference buffer solutions (certified reference material (CRM)) additionally fulfill all requirements of regulated industries.
Temperature curves of CPY20 pH buffers are pre-programmed in all Liquiline series transmitters to simplify sensor calibration and adjustment, reducing your maintenance effort.
