1.0 Introduction
1.1 TE-PRO-CAL Overview
The TE-PRO-CAL is an advanced low volume calibrator that can be used to
calibrate low-volume air sampling equipment such as the TE-Wilbur low
volume sampler, the BGI PQ200, Thermo Partisol and other low-volume
instruments that operate at 16.67 lpm. The system utilizes a precision-
machined venturi to generate a differential pressure proportional to the flow
rate that is not affected by temperature variations or humidity. The calibrator
is mounted directly to the sampler’s inlet downtube for ease of use and quick
calibration of field instrumentation. The calibrator is powered by 4 AA
batteries. The system is shipped with the calibrator, a NIST traceable
calibration certificate, 4 batteries, a filter temperature probe and rugged
carrying case. With four generations of experience, leadership, and know-
how, the Tisch family would like to welcome you to our company and thank
you for choosing Tisch Environmental products.
