RKI Instruments Isobutane 50% LEL Mid-Cap Alum 58L – 722-002

RKI Instruments 722-002 Isobutane 50% LEL Mid-Cap 58L Aluminum System

The RKI Instruments 722-002 isobutane mix reference standard leverages a medium-capacity 58-liter aluminum cylinder and high-fidelity gas composition to deliver elite metrological stability for heavier hydrocarbon detection. Achieving ±2% analytical accuracy, this assembly provides a high-fidelity reference for 50% LEL Isobutane (C4H10) in an air balance, ensuring precise characterization of combustible gas sensors. The sophisticated internal architecture maintains measurement repeatability over a 48-month shelf life, ensuring strict compliance with NIST-traceable standards for industrial safety environments.

Technical hardware integration features a C-10 (5/8″-18 UNF) valve type and a 500 psig pressure rating to facilitate rapid stabilization during critical field-based metrology audits. This assembly incorporates laboratory-grade gas fidelity produced in the USA, optimized for high-stakes industrial verification 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 a factory-characterized reference grade included for immediate site readiness. Experience superior metrological calibration precision with this RKI Instruments assembly, designed for premium performance.
