RKI calibration kits for fixed gas transmitters bundle a certified calibration gas cylinder with a regulator, cal cup or gas bag, and carrying case — everything needed to field-calibrate a specific RKI fixed instrument model. Each kit is matched to its transmitter's gas type, connection, and cylinder size requirements. The configurations listed here cover the most commonly ordered kits for the Digester Gas Monitor, T2A/T3A/AirLink 6900/6940XP, VOC Pro, and general fixed transmitter families (GD-A8V and similar). Additional gas types and instrument-specific kits are available by quote — see our full RKI Instruments Parts & Accessories collection for calibration gas cylinders sold separately.
