MSA 10048279 Econo-Cal 34L Calibration Gas Cylinder 100 PPM Isobutylene

The MSA 10048279 is an Econo-Cal™ aluminum calibration gas cylinder containing 100 PPM Isobutylene in Air, packaged in a compact 34-liter size. It is part of MSA's complete line of calibration gas cylinders designed to accurately calibrate and bump test portable gas detectors, including MSA ALTAIR and Sirius series instruments equipped with PID/VOC sensors.

The gas mixture is prepared gravimetrically using NIST-traceable weights, ensuring certified accuracy and reliability. Each cylinder is individually labeled with its lot number and the nominal value of the gas constituents. This non-reactive isobutylene/air mixture is the required calibration gas for MSA instruments equipped with a 0–2000 PPM PID sensor.

Key Features:

• 100 PPM Isobutylene in Air — the standard calibration gas for PID/VOC sensor instruments
• 34-liter capacity in a compact, lightweight aluminum cylinder
• Pressurized to 500 psig for consistent, reliable delivery
• NIST-traceable gravimetric gas mixture certification
• Individual certificate of analysis and MSDS included with each cylinder
• Compatible with MSA Model RP regulator (sold separately)
• Includes RFID collar for use with MSA GALAXY® GX2 Smart Cylinder Holder
• Suitable for calibration and bump testing of MSA ALTAIR 5X (PID), Sirius, and other MSA multi-gas detectors
