Thermo Scientific™ Orion™ Conductivity Calibration Standards

Ensure accurate, reliable conductivity measurements with Thermo Scientific™ Orion™ Conductivity Calibration Standards, formulated for precision electrochemical analysis in both laboratory and field environments. These ready-to-use standards are traceable to NIST™ Standard Reference Materials (SRMs), supporting calibration accuracy, regulatory compliance and data reproducibility across a wide range of applications.

Key Features and Benefits

• Traceable to NIST SRMs for accurate, compliant calibrations
• High reproducibility for consistent results across labs and operators
• Broad application use across QA/QC, environmental, industrial and research laboratories  
• Optimized for Orion conductivity meters and electrode with integrated temperature compensation support

Designed for routine calibration and verification of conductivity meters and electrodes, these standards help reduce measurement variability and maintain consistent system performance. They are suitable for use in environmental monitoring, water and wastewater testing, food and beverage analysis and pharmaceutical quality control and manufacturing.

Complete Range of Conductivity Standards

Thermo Scientific Orion conductivity standards are available across a broad range of conductivity values to support everything from ultrapure water measurement to high-conductivity industrial samples. Common calibration points include:

• 100 µS/cm – ideal for low conductivity and purified water applications
• 147 µS/cm – for industrial calibration and method validation
• 1413 µS/cm – general-purpose calibration for routine lab and field testing
• 12.9 mS/cm (12,900 µS/cm) – suitable for higher conductivity samples
• 111.9 mS/cm (111,900 µS/cm) – suitable for higher conductivity samples
• 0.1 M KCl standards – for precise electrochemical calibration and method validation

Designed for compatibility with Thermo Scientific Orion conductivity meters and electrodes, including both 2-cell and Thermo Scientific™ DuraProbe™ 4-cell conductivity electrodes. Built-in temperature compensation tables in Orion meter software streamline calibrations by enabling automatic adjustments, reducing user error and saving time.

Pouch vs. Bottle Formats

Orion conductivity standards are available in 20 mL single-use pouches and 60 mL bottles to fit different workflows. Both formats deliver the same NIST-traceable accuracy and formulation consistency, enabling flexible use without compromising data quality.
