cylinder from Calgaz.
NOTE: Both the AirCal 1000 and the Ozone calibrator take time to warm up and become stable.
Turn on the AirCal 1000 and switch on the pump override switch on the back panel for at least
30 mins before staring calibration.
Turn on the Ozone generator and set it to deliver 0.1 ppm Ozone for at least 30 mins before
starting calibration, this allows time for the lamp in the ozone generator to stabilise at 0.1
ppm.
Calibration gases
Aeroqual cannot supply calibration gas cylinders, these must be purchased locally. Aeroqual
recommends small size portable gas cylinders be purchased from Calgaz:
