FEATURES |
|
| VERSATILE, RUGGED DESIGN |
The Model 901 is a battery-operated,
portable oxygen analyzer used for the measurement of residual oxygen in
gas-flushed (CAP/MAP) food packages. This hand-held unit can be used by
non-technical personnel where you need it, in the lab or at the packaging
line, or it can be easily transported to other locations. The Model 901
is powered by Ni-Cad rechargeable batteries, with typically 8 hours of
operation before recharging is required. |
| FOOD APPLICATIONS |
The Model 901 design has proven itself
in hundreds of installations for food applications such as meats, fresh
produce, pasta, nuts, snackfoods, dairy products and coffee. The sensor
is unaffected by high levels of background gases such as nitrogen or carbon
dioxide. The Model 901 can also be used for applications where the oxygen
level is very high (50 to 100%), without overloading the sensor. It is
unaffected by trace hydrocarbons or high levels of CO2, which can poison
other types of sensors. |
| EASY SAMPLING & ANALYSIS |
The Model 901 sample probe is tipped
with a particulate filter and luer fit syringe needle with side-port holes
to prevent plugging. Sample is drawn through the probe and turbing and
then to oxygen sensor when the pump is turned on. The pump is electronically
timed to draw in the precise amount of sample required for the analysis,
and then turns itself off after the pre-set sampling time (5 to 10 seconds).
Th eoxygen concentration is read on the display. |
| LOW COST |
| The Model 901 is cost effective, reliable alternative to other analyzers. Not only is the initial costs are lower as well. When service is required, units are generally repaired and returned the same day as received to minimize down-time. |
| PRINCIPLE OF OPERATION |
The Model 901 uses a syringe needle
sampling assembly to pierce the package and draw a sample into the analyzer
sensor for oxygen measurement. The sensor signal is converted to per-cent
centration and displayed on the LCD screen The oxygen sensor used in the
901 was specifically designed for gas-flushed packaging measurements.
the sensor is a proprietary electrochemical design which is inexpensive,
quick to respond, requires minimal power and has excellent zero and span
stability. Unlike zirconia sensors which are heated to 500-600°C, the
901 sensor will not crack when exposed to liquid water drolets and is
unaffected by trace hydrocarbon gases. |
