4146 (0.01-20 LPM) by TSI - Primary Calibrator Plan:8 Day Replaces the standard CO sensorThe Primary Calibrator 4146 by TSI is a field portable volumetric flow calibrator covering a range of 0. 0120 LPM with a clear digital display for real time flow rate readout while making pump adjustments. Traceable to NIST standards and featuring a dampening chamber module to stabilize pulsating pump flow, it delivers accurate, documented flow verification across both low and medium flow ranges. It is ideal for calibrating personal air sampling pumps
