TSI 4046 Primary Air Flow Calibrator for 2.5 to 300 LPM
The accuracy of a sampling pump depends on two things: (1) how much air passes through the sampling media and (2) good laboratory analysis. As a common practice, sampling pumps should be calibrated before and rechecked after sampling.
The TSI 4046 primary calibrator continuously shows volumetric flow rate on its clear digital display, so it's easy to make pump adjustments, calibrations, and periodic flow checks in real time. The TSI 4046 is accurate to within ﾱ2%.
