Calibration Kit Compact and completely portable, this self-contained calibration kit can be readily used at the sampler site. The sampler flow indicator should be calibrated at least every three months and after every brush or motor change to maintain air volume accuracy.
Air flow is varied by means of a series of load plates.
The calibration orifice should be re-certified annually according to Federal guidelines. By rotating the knob, filter resistance is simulated permitting calibration of the flow indicator at various points on the manometer. The calibration orifice should be re-certified annually according to Federal Guidelines. The G40 Calibration Kit is recommended for calibrating the Model GPS1 Puf Sampler. The calibration orifice should be re-certified annually according to Federal Guidelines.
