INTRODUCTION
D16 PortaSens III
The
D16
PortaSens III
is a rugged,
hand-held device used to detect leaks
of toxic, or otherwise dangerous gas,
and also to detect oxygen deficiency.

Gas Leak Detector.
The D16 quickly adapts to measure
different gasses by inserting the
appropriate H10 gas sensor module,
which retains all of the calibration and
configuration settings for the target
gas.
An internal pump with a flexible
wand is included for point sampling
around suspect pipe fittings and
confined spaces.
Readings and settings are
presented on a backlighted, resistive
touch, color graphics LCD, with a
beeper to notify you of alarms and
other events.
Readings are recorded in .csv files
(ASCII text, comma-separated values)
and transferred to a PC using the
supplied USB cable. No external
application is required. The files may
be opened with any text editor, or
directly by applications like Microsoft
Excel®.
Power is provided from a
rechargeable, NiMH D-cell battery. The
battery should be removed and charged
in an external charger after each use.
The battery is not used or even
required when the device is connected
to a USB port.
Inlet and Outlet Ports
The inlet port, located on the
manifold lid, is fitted with a quick-
disconnect fitting to connect the
flexible wand (see Figure 2 on page 8).
The wand can be used for probing
closely around pipes and fittings, and
for sampling confined spaces without
entering. The wand is lined with
Teflon™ and is inert to nearly all
vapors and gasses.
Flexible tubing may be connected
to the inlet port to sample high gas
concentrations, or those beyond the
reach of the wand. Fluorocarbon-based
tubing is strongly recommended for
measuring low concentrations of
reactive gases. Other materials may be
used for high range measurements,
where the adsorption of gas by the
tubing is negligible, or where you are
probing for significant leaks.
The internal walls of the wand and
any inlet tubing must be kept dry.
Water on the walls may absorb soluble
gases and decrease the gas readings,
presenting an unsafe condition. If the
inside of the wand or tubing gets wet,
draw dry air through it for 10 to 15
minutes.
Keep the inlet and outlet ports
free of obstructions.
