Isobutylene Calibration Gases

Commonly used for calibration of PID instruments. 

100 PPM Isobutylene is the standard factory calibration gas value for most PPM level PID detectors.

10 PPM Isobutylene is the standard factory calibration gas value for most PPB level PID detectors. This includes the RKI GX-6000 with PPB level PID sensor and the Honeywell Rae Systems PPBRae 3000.
