The Z series of oxygen analysers feature
sensors based on zirconium oxide technology.
They have the advantages of fast response
times, excellent accuracy at ppm levels and
a non-depleting sensor for long life. A range
of different configurations and internal sample
systems are available – so we can find the
product that is right for you.
Choose the Z230 for versatility and
portability. This benchtop analyser is a fully
self contained, complete unit with integral
sensor and pump (optional). The carrying
handle makes it easily transportable and
the integral flowmeter and valve mean there
are no further accessories or consumables
to carry around. The analyser features
bi-directional RS232 allowing remote
calibration and datalogging. There is a choice
of outputs and both outputs and alarms are
user programmable. The internal pump option
is chosen if there is insufficient flow in the
sample stream and, for applications where a
long sample path is involved, a bypass flow
sample system enables faster results.
Not all zirconia sensors are the same.
Hitech Instruments manufacture zirconia
sensors in-house. Careful choice of raw
materials and Hitech’s manufacturing ‘know

how’ result in a fast responding, robust sensor
with excellent specification and a very fast
warm-up time. Different sample systems are
available for applications involving long sample
paths and high pressure. Bespoke designs are
also available according to the application.
Oxygen is measured in a wide variety
of processes to confirm the presence
or the absence of it. The most common
application is to measure oxygen as the
impurity in other gases, e.g. nitrogen
generators. Oxygen is required in aerobic
processes and situations that require user
intervention, e.g. to ensure that it is safe to
enter a chamber for maintenance work. Some
processes require the absence of oxygen to
be efficient, e.g. furnace atmospheres, others
just require a low level of oxygen for safety
reasons, e.g. inert gas blanketing.
Hitech offer a number of different
solutions for oxygen measurement
dependent on the application. Our technical
sales engineers will be pleased to advise the
system that is right for you.
