* The O 2 bump test can also be performed by exhaling on the sensor inlet for
approximately three to five seconds.
** MSA recommends calibration of the ClO 2 ALTAIR Pro Detector using a ClO 2 generator
for most accurate calibration. This instrument has a cross-sensitivity factor to Cl 2 of:
2 ppm Cl 2 equals approximately 0.8 ppm ClO 2 .
