CAUTION:
The DTEX system is designed to evaluate odor inten-
sity in gas streams. Because of the potentially haz-
ardous nature of conditions and elements involved in
conducting tests, users are reminded to use extreme
caution while operating the DTEX system. The system
operated improperly or past due calibration could cre-
ate a dangerous situation to both persons or property
as well as produce inaccurate test results. *Refer to
D6273-98 ASTM Standard Test Methods for Gas
Odor Intensity for guidance regarding precautions,
hazards and procedures.
Introduction
Congratulations on your purchase of the DTEX
DX 1000G/L odorant detection system. You’ve
made a wise investment for your company.
DTEX is a small, handheld instrument, which
assists the user in determining the odorant
intensity of Natural Gas/LPG with menu-driven,
step-by-step instructions. After connecting to
the sample point, sniff test completion times
typically run 2 to 3 minutes. The DTEX system
displays the actual air/gas percentage, pres-
ent in the device, thus eliminating the need for
flow tubes and cross-reference charts. With an
on-board database of 50 test locations, DTEX
can record multiple tests for each test location,
including Threshold Detection Level (TDL) and
Readily Detectable Level (RDL)
readings and
test notes, such as odor intensity ratings, weath-
er conditions, etc. Then, DTEX goes one-step
further by storing up to 75 complete test results
electronically. Back at the office the test results
can be individually reviewed or downloaded into
a PC. It’s that simple.
Other important features of the DTEX system
are:
•Intrinsically safe for hazardous locations
Class 1, Division I, Groups C&D
•Low power circuitry
•Rechargeable battery
•Rugged enclosure
•Completely portable
•Ergonomically designed for compatible
operator interface
•Odorant level detection reports are no
longer manually written
This Manual Covers both versions, Natural Gas
and LPG. Applies to DTEX 1000 G and L.
