PHA-SERIES

Supported Applications

The Omega PHA-Series consists of pre-mixed pH calibration solutions designed for the maintenance and verification of pH measurement systems. These liquid standards provide a known reference point to ensure sensor accuracy during routine instrument checks.

Operating Conditions & Performance

This series provides specific, stable pH values required for calibrating sensors across different acidity and alkalinity ranges. The solutions are formulated as pre-mixed liquids ready for immediate use in calibration procedures without requiring dilution or preparation by the end user.

Available Calibration Points

The series includes variants corresponding to specific pH levels:

• pH 4.01 (PHA-4)
• pH 7.00 (PHA-7)
• pH 10.01 (PHA-10)

Additionally, the series offers DI water variants for rinsing or zero-point checks:

• DI Water (PHA-DI)

Configuration Options

The PHA-Series is available in multiple container sizes and packaging configurations to accommodate different laboratory volumes and usage frequencies. The product line includes standard bottles as well as gallon-sized containers for higher-volume applications.

Packaging Options

• Standard bottle size (e.g., PHA-4, PHA-7, PHA-10)
• Gallon container size (indicated by the -GAL suffix in part numbers such as PHA-4-GAL and PHA-7-GAL)

Specialized Variants

The series includes specific model codes for distinct formulations:

• PHA-DI: Deionized water solution.
• PHAB-PH and PHAB-DI: Variants designated with the PHAB prefix, available in pH standard and DI configurations respectively.
• PHA-10-CAL-PH: A specific variant of the pH 10 calibration solution.

Key Product Differences

Variants within the PHA-Series are distinguished primarily by their target pH value and container volume. The part number structure indicates these differences:

• The numeric suffix (4, 7, or 10) identifies the specific pH calibration point.
• The -GAL suffix denotes a gallon-sized package compared to standard bottle sizes.
• The prefix PHAB- distinguishes a separate product line within the series offering similar DI and pH solutions.
