Ntron Microx Specifications

Microx

Oxygen Analyser

Zirconia Technology

The Microx is a highly reliable

and cost-effective Oxygen

Analyser with a linearized 4 to

20 mA output and 3 alarm

outputs. It has a detection

range of 0-1% Oxygen.

This compact analyser utilises

Zirconia technology to give a

reliable and fast response time,

long life and minimal drift of

oxygen measurement.

EXCELLENCE
THROUGH DIVERSITY

Proven Sensor Technology

The compact Zirconia sensor offers a simple
and effective method for installation into
OEM equipment. The robust design of the
sensor assures accurate measurement as
well as a quick response characteristic to
serve a wide range of oxygen measurement
applications.

A major advantage of the Ntron Zirconia
sensor is fast response time from ambient
air to low PPM Oxygen Measurement.
Additionally, there exists no real limitation
on shelf life or storage temperature. Perhaps
the most attractive feature of the Ntron
Zirconia Sensor is its long life. Expected

operating life is five years under normal

operating conditions.

Low Maintenance and Cost
of Ownership

The Ntron Zirconia Oxygen sensor has an
extremely long life expectation in the region
of 5 years under normal operation. Due to
the highly stable nature of the sensor, a
calibration interval of once per year is

required, allowing for significant cost

savings.

Minimal Sample requirements

Due to the unique construction of the
Zirconia Oxygen sensor, only 100 mLPM
sample is required.

Fast Response Time

Due to its miniature size and unique design,
the Ntron Zirconia sensor has a T 90 of less
than 10 seconds.
