The high-quality CPY20 buffer solutions provide the highest-precision pH calibration. They are produced and bottled in calibration laboratories that are permanently accredited by the authoritative DAkkS (German accreditation body). The accuracy of the buffer solutions is +/-0.02 pH; they are prepared using NIST and PTB standards and contain only FDA-approved preservatives. With CPY20 you obtain reliable, accurate values.
Benefits
Highly accurate, reproducible buffer solutions help you optimize pH measured values in the process and increase product yield and quality
CPY20 pH buffer solutions are prepared in accordance with NIST (USA) and PTB (Germany) standards, are traceable and meet strict documentation requirements over their service life
All preservatives used are FDA-approved media, ensuring maximum product safety
The temperature curves of the CPY20 pH buffer solutions are preset in the Liquiline series transmitters for convenient sensor calibration and adjustment, reducing maintenance workload
Easily accessible buffer solution certificates simplify your audit trail and increase SOP reliability
Applications
CPY20 pH buffer solutions are used for calibration and adjustment of pH electrodes in all industries, suitable for the daily calibration of high-precision sensors in production processes and laboratories
