Standalone calibration accessories for RKI gas detectors — dispensing valves and regulators for standard CGA-600 calibration gas cylinders, calibration caps and cups for specific instrument models, and replacement gas sample bags for use with calibration kits.

These sell separately from a complete calibration kit for facilities that already own a cylinder and regulator, or need a replacement part. See our full RKI Instruments Parts & Accessories collection for complete cylinder and calibration kit bundles.
