The Z1110 zirconia oxygen
analyser measures oxygen concentrations from percentage levels
to fractions of parts per million
(ppm) in clean gases. Packaged in
a robust wall mounting enclosure, it
uses a zirconia oxygen sensor to
provide accurate measurement with
minimal interference from other
gases. The unique cell and heater
design gives a very fast warm-up
time, rapid response, and long sensor life. A choice of sampling
options is provided to produce
virtually custom-built systems.
A large multi-digit autoranging LCD is used to display measured concentrations and the useradjustable parameters in configuration mode.

Two alarm channels each provide one set of volt-free changeover
contacts. They can be user-configured to any concentration within
the span of the instrument, as well
as function (high, low or off) and
hysteresis. A choice of two analogue outputs is available, 0 to 5V
or 4 to 20mA, fully programmable.
The standard sampling system comprises a metering valve
and flowmeter. Standard alternatives are available to cover a wide
variety of applications. Hitech also
supply a range of sample conditioning accessories to cater for
most sample sources.
