Frequency of calibration
The document outlines calibration frequencies for parts in a high-volume sampler and stack monitoring kit. For the high-volume sampler, the blower, rotameter, and time totalizer should be calibrated once every six months or when replaced. For the stack monitoring kit, the pitot tube, rotameters, pyrometer, stop watch, pressure gauge, thermometer should be calibrated after every 10-15 uses to ensure accurate flow and concentration measurements. If the parts are not properly calibrated, the measured flow and concentration results will not be correct.
