Endress+Hauser CPY3 Buffer Solution: Reliable Calibration pH Excellence

For process and water quality professionals, measurement accuracy is non-negotiable. The Endress+Hauser CPY3 Buffer Solution is the trusted standard for precise and reliable calibration of pH sensors. Specifically, the CPY3-4 formulation provides a stable reference point to validate and adjust your analytical instrumentation, ensuring your pH measurements are consistently trustworthy.

Why Choose CPY3 Buffer Solutions for Your pH Calibration?

Calibration is the cornerstone of accurate pH measurement. Our CPY3 buffer solutions are engineered to deliver:

Certified Accuracy: Precisely defined pH values with documented traceability to international standards (NIST/DIN), guaranteeing confidence in your calibration process.

Unmatched Stability: Resistant to chemical interference and atmospheric CO₂ absorption, providing a stable reference potential for both routine checks and demanding applications.

Optimal Sensor Care: Formulated to be gentle on pH-sensitive glass membranes and reference systems, supporting longer sensor life and reduced maintenance costs.

Broad Compatibility: Designed for seamless use with all Endress+Hauser pH sensors, including the innovative, digital Memosens technology and traditional analog sensors.

Key Features of the CPY3-4 Buffer Solution

pH Value: Precisely at pH 4.01 at 25°C (77°F)

Primary Application: The essential low-point calibration buffer for a standard two-point calibration (typically paired with CPY3-7 or CPY3-9).

Temperature Compensation: Values are clearly listed for a wide temperature range for accurate adjustments.

Packaging: Available in practical, sealed bottles and larger containers to suit every lab and field need.

Applications Across Industries

The Endress+Hauser CPY3 buffer solution is indispensable wherever precise pH monitoring is critical:
