Pump Calibration

CALIBRADOR para bombas de alto y bajo caudal

Primary Calibrators

Personal sampling pumps are key tools for exposureassessment. The accuracy of sampling depends onhow much air passes through the sampling mediaand good laboratory analysis. As a common practice, samplingpumps should be calibrated before andrechecked after sampling using a calibration device.
TSI offers two Primary Calibrator models for calibrating pumps or any other air sampling instrumentthat draws an active air sample. The Model BL302B Primary Calibrator offers a range of 0.01 to 20 lpmand the Model BL302A, from 2.5 to 300 lpm.These small, portable, battery-operated units arelightweight and easy to use. Volumetric flowrate is displayed continuously so adjustments to pumpflow can be made in real-time. These PrimaryCalibrators are temperature-compensated and pres-sure-corrected to calculate volumetric flow rate atan accuracy within 2% of reading.Primary Calibrator kits are available complete with asoft-sided carrying case, battery pack, tubing, userguide and NIST-traceable calibration certificate.
