CDS-SERIES

Supported Applications

The Omega CDS Series provides Conductivity and Salt % Calibration Solutions designed for calibrating conductivity instruments. The series includes standard solutions covering a range of microsiemens per centimeter (µS/cm) values as well as sodium chloride (NaCl) concentrations.

Operating Conditions & Performance

The CDS Series delivers ±1% Accuracy across its measurement ranges. Solutions are available in conductivity levels including 10 µS/cm, 15 µS/cm, 45 µS/cm, 450 µS/cm, 1413 µS/cm, 1500 µS/cm, 4500 µS/cm, 15000 µS/cm, and 45000 µS/cm. Salt-based standards are offered as 1% NaCl and 10% NaCl solutions.

Shelf life varies by model: most solutions have a 1-year shelf life, while CDSA-10* and CDSA-15* carry a 6-month shelf life. The series is RoHS compliant. A NIST Certificate of Conformance is available as an optional certification.

Configuration Options

The series supports multiple configuration options to accommodate specific calibration needs:

• Conductivity Ranges: Models span from 10 µS/cm up to 45000 µS/cm, including intermediate points such as 1413 µS/cm and 1500 µS/cm.
• Salt Concentrations: Available in 1% NaCl (CDSA-1-NACL) and 10% NaCl (CDSA-10-NACL).
• Certification Options: Add the suffix "-CAL-CDS" to any model number at time of purchase to include a NIST Certificate of Conformance.
• Housing Accessories: The PHA-77 Third-Arm Electrode Holder is offered as an accessory for use with these solutions.

Model numbers follow the pattern CDSA-<value>, such as CDSA-45, CDSA-1413, or CDSA-1-NACL. The PHA-77 electrode holder is ordered separately.

Key Product Differences

Variants within the series are distinguished by their specific conductivity value or salt concentration:

• CDSA-10* and CDSA-15*: Low-range solutions (10 µS/cm, 15 µS/cm) with a noted 6-month shelf life.
• Standard Conductivity Models: Includes CDSA-45 through CDSA-45000 for mid-to-high range calibration points.
• Salt Solutions: Distinct models CDSA-1-NACL and CDSA-10-NACL provide 1% and 10% NaCl concentrations respectively.

Note: Ordering a NIST Certificate of Conformance requires adding the "-CAL-CDS" suffix to the model number, which incurs an additional cost and setup charge.
