TIGER & TIGER LT instruments have space in the case for one cylinder 44L or 116L size. Tiger users would normally use 100ppm Isobutylene and 0.5 LPM regulator although the unit can be calibrated with any PIDable cal gas and with a 0.5 LPM or demand flow regulator.
TIGER SELECT users have more choices. The most popular cal gas is 5ppm Benzene for both the TAC and tube modes although some users like to calibrate the TAC mode with Isobutylene to reduce the benzene cal gas used. As with the Tiger the case has space for one 44L or 116L cylinder and you can use either a 0.5 LPM or demand flow regulator.
CUB units can be manually calibrated using a 0.5 LPM regulator and single gas mixture, PPM and PPB units are calibrated with 100ppm Isobutylene while TAC units are calibrated with 5ppm Benzene. If you have the calibration docking station you need an demand flow regulator. When using the docking station the 116L cylinder is preferred.
TITAN units must be used with an demand flow regulator and are normally calibrated with 5ppm Benzene. Due to the time a cal cycle takes it is advised to use the 116L cylinders.
TVOC & FALCO units need 10ppm, 100ppm, or 1000ppm Isobutylene depending on the range being used. A non pumped setup should be calibrated with a 0.5 LPM regulator while a pumped configuration should use an demand flow regulator.
