- Abstract
- The purpose is to explain the maintenance, calibration, and operation of the isokinetic source-sampling equipment. This procedure has been used satisfactorily and is presented as a guide to assist interested personnel in using the equipment. The sampling train has four major componets: (1) the pitot assembly, which includes the probel nozzle, a heated glass probe, and a pitot tube for monitoring gas velociety during sampling; (2) the meter box assembly, which consists of a system of manometers and orifice meter, a vacuum pump, a dry gas meter, and electrical controls for sampling (3) the sample box assembly, which contains the glassware; and (4) the umbilical cord which connects the sample box with the meter box. The maintenance and calibration procedure described for each of the components should be followed in the shop or laboratory in preparation for each sampling test.
