Endress+Hauser CPY3-5 Buffer Solution Calibration Precise pH Measurement

Accurate pH calibration is the foundation of reliable process control. The Endress+Hauser CPY3-5 Buffer Solution is a high-quality, certified reference material designed for the precise calibration and validation of pH electrodes, specifically targeting the neutral point (pH 7) and mild alkaline conditions.

Why Choose the CPY3-5 Buffer Solution?

This ready-to-use buffer solution guarantees traceable accuracy and stability for your critical pH measurements in laboratories, water treatment, pharmaceutical, food & beverage, and chemical processes.

Key Features & Benefits:

Certified Accuracy & Traceability: Formulated to deliver a highly accurate pH value of 4.01, 7.00, or 9.21 (depending on variant) at 25°C (77°F), with direct traceability to international standards (NIST/DIN).

Outstanding Stability: Its low conductivity and robust chemical composition ensure minimal drift, providing a stable reference point for consistent, repeatable calibrations.

Process & Laboratory Use: Ideal for both field calibration of industrial sensors (like Endress+Hauser CPY, CPS, and other brands) and benchtop use in quality control labs.

Prevents Contamination: Packaged in chemically resistant, sealed bottles to maintain purity and prevent atmospheric CO₂ absorption, which can alter pH.

Simplifies Compliance: Supports compliance with quality standards (ISO, GMP, FDA) by providing documented calibration reliability for audits.

Primary Applications:

Calibration of pH sensors and analyzers in industrial processes.

Quality assurance and control laboratories.

Environmental monitoring and wastewater treatment.

Pharmaceutical and biotech manufacturing.

Food and beverage production.
