Welcome to Cal Gas Direct

NIST-Traceable Isobutylene (C4H8) Calibration Gas: The universal reference standard for Photoionization Detectors (PIDs) and volatile organic compound (VOC) monitoring. Fully compatible with RAE Systems, Ion Science, Industrial Scientific, Honeywell, and Dräger gas detection instruments.
Isobutylene is the worldwide surrogate standard for calibrating 10.6 eV and 11.7 eV PID lamps. It enables precise response factor calculation for detecting benzene, toluene, xylene, solvents, and fuel vapors during EPA Method 21 monitoring, environmental remediation, and confined space entry.
Direct-match replacements for RAE Systems 600-0002-000, Ion Science, and Industrial Scientific blends. Available in disposable steel (103L, 34L), lightweight aluminum (58L, 116L), and 17L field cylinders fitted with standard C-10 (5/8"-18 UNF) or CGA-600 connections.
