PORTACAL® Isobutylene (C₄H₈) Calibration Gas is designed for the calibration, bump testing, and verification of compatible isobutylene gas detectors, photoionization detectors (PIDs), VOC sensors, and monitoring instruments.

Isobutylene (C₄H₈), also known as isobutene, is a colorless, flammable hydrocarbon gas commonly used in industrial and chemical applications. Isobutylene is also widely used as a reference gas for calibrating photoionization detectors (PIDs) used to detect and measure volatile organic compounds (VOCs).

PORTACAL® Isobutylene Calibration Gas provides a known concentration of isobutylene to help verify that compatible PID instruments, VOC sensors, portable gas detectors, and gas monitoring systems are functioning and responding properly.
