RKI Instruments 4-Gas Mix Fleet-Service (58L) – 72-5201RK-12

RKI Instruments 72-5201RK-12 4-Gas Mix Fleet-Service 58L Aluminum System

The RKI Instruments 72-5201RK-12 4-gas mix reference standard utilizes a specialized 58-liter aluminum high-pressure cylinder and high-fidelity gas composition to deliver elite metrological stability for fleet calibration audits. Achieving ±2% analytical accuracy, this assembly provides a high-fidelity reference for H2S (25 ppm), CO (50 ppm), CH4 (50% LEL), and O2 (12%) in a Nitrogen balance. The sophisticated internal architecture maintains measurement repeatability through reactive gas stability over a 24-month shelf life, ensuring strict compliance with NIST-traceable standards for multi-gas instrument compliance testing.

Hardware specifications include a standard C-10 (5/8″-18 UNF) valve interface and a 500 psig pressure rating to facilitate rapid stabilization during critical calibration audits. This assembly incorporates laboratory-grade gas fidelity produced in the USA, optimized for industrial environments where non-flammable UN1956 classified gas is required for premium metrological performance. Safety is prioritized through the aluminum cylinder’s corrosion-resistant build, allowing technicians to perform precision verification with laboratory-grade signal integrity and full NIST traceability included for immediate site readiness. Experience superior metrological calibration precision with this RKI Instruments assembly, designed for premium performance.
