Factory Recalibration Interval: 1 year
In order to provide a back up for the on-line analyzers, colorimetric indicator tubes
(National Draeger, Inc., Pitt._.burgh,Pennsylvania) were used for the selected gas
measurements. Irl add!tion to the tube measurements indicated in Fig. 1,tubes for
H_Sand SO2were employed for certain tests. These tubes are normally used with
lt a hand pump for atmospheric sampling. They may, however, be advantageously
used with personal sampling pumps where the sampling rate and duration are
carefully measured. The six tubes were connected to individually
calibrated sampling pumps (DuPont Alpha 2 and DuPont P-4000, DuPont
Company Instrument Systems, Kennett Square, Pennsylvania) and operated for
exactly ten minutes at sampling rate: of 1O0 mL/minute or 50 mL/minute,
depending on the range of each individual tube. The Draeger tube_ were chesen
because of their low pressure drop at the specified flow rate. Their specificity for
the target compound is typically very good, and possible interferences are well
documented by the manufacturer. For ease of use and deployment, ali the Draeger tubes with their associated pumps
as well as the triple sorbent traps and pumps were mounted on a 3 ft x 6 ft board.
A stainless steel tube manifold with quick connect tube fittings was mounted at the
top of the board. Rapid connection of the unit to the overall sampling train as
well as change of individual tubes and pumps was facilitated. Flow rates through
the Draeger tubes were carefully chect:ed prior to each test run using a volumetric
standard (Buck model M-5 primary gas flow calibrator, A.P. Buck Inc., Orlando,
FL.) .
Pump calibration was crucial to the accuracy of the measurements.
Careful volumetric determinations were made prior to and subsequent to each test or run.
Volumes were checked using a Buck Model M-5 Primary Gas Flow Calibration
(A. P. Buck, Inc., Orlando, Florida). During operation, ali pumps were started
immediately prior to a test firing and were allowed to run exactly ten minutes.
The pump flow rate settings were such that the volume of air drawn through each
tube made the tube direct reading in average concentration over a 10 minute
sampling time. That is, if the stain reached the 10 ppm line over the course of the
10 minute sampling period, that meant that the concentration in the chamber
averaged 10 ppm during that time period.
Detects a variety of gases and vapors with one hand operation. Automatic stroke counter eliminates the potential for human error. Easy-to-read stroke indicator "blinks" after proper amount of air has been drawn for successful sampling. Comfortable hand grip can be used even with gloves. Includes remote sampling adapter and handy carrying pouch. 10' sampling line and detector tube handbook sold separately. Interchangeable with Draeger tubes and pumps.
