Introduction
The Rapidox 1100ZR-H-OL-LC (Z= zirconia sensor R=rear panel gas connections
H=Heller OL=Open Loop LC = Low Cost Version) oxygen analyser allows fast
and accurate oxygen analysis over the oxygen range 1ppm to 100% O
2
. The
analyser provides continuous on-line oxygen analysis, with a typical response
time of less than 4 seconds for a 90% response to a step change in gas
compositions.
The Rapidox 1100ZR-H-OL-LC is a fully integral unit complete with a powerful
diaphragm pump to provide variable gas sampling up to approximately 1.2 litres
per minute.
The sensor head is located inside the analyser and comprises a zirconia ceramic
tube that needs to be heated to 650°C before it will conduct oxygen ions. The
analyser supplies heat to the sensor, which is controlled very accurately by a
regulated power supply incorporated in the instrument. An internally mounted
pressure sensor compensates for any fluctuations in pressure or vacuum caused
by differing flow conditions.
The analyser is packed with features including programmable alarm circuits,
programmable analogue outputs, easy calibration (user selectable gases), RS232
communications and complete communications / data-logging software.
