GDS Corp Gas Calibration Kits are designed to provide the most accurate reference source available for single, dual and multiple gas mixtures. Each cylinder of calibration gas has traceability to NIST standards, ensuring accurate and repeatable calibrations.

GDS Corp Gas Calibration Kits are available for the following gases: Ammonia, Carbon Dioxide, Carbon Monoxide, Chlorine, Hexane, Hydrogen, Hydrogen Sulfide, Hydrogen Cyanide, Isobutylene, Methane, Nitrogen Dioxide, Oxygen, Sulfur Dioxide and more. Specialized gases are available upon request.

For highly corrosive gases with short shelf-life, including chlorine and chlorine dioxide, field-based gas generators such as the CAL 2000 are recommended for long term use where periodic calibration is done more than once a year.
