Dual Oxygen Analysers
Two switch selectable Oxygen Analyser
Modules give % and PPM range
measurement respectively.
Zirconia Sensor Technology
At the heart of the Ntron Yellow Box
Portable Analyser are two Solid State
Zirconia Sensors for long life, high stability
accurate ZRO2 measurement of % and PPM
Oxygen Concentrations.
Minimal Sample requirements
Operating the Yellow Box Portable Analyser
is made very simple by the internal sample
system. Taking a gas measurement only
requires the operator to connect the gas
line, purging for a few seconds and
switching the valve position. When not in
use, the sensor is isolated from the ambient
air and process sample.
Fast Response Time
Due to its reduced size and unique design,
the Ntron Zirconia ZRO2 sensor has a T 90
of less than 10 seconds.
