Product Description

The OXY-SEN™ Oxygen Monitor is an economically priced
percent oxygen measuring system equipped with a standard
measuring range of 0-100%. Available as an option, are dual
4-20 mADC recorder outputs that are scaled over 0-100%
and 0-25%. The instrument features an extended life, am­bient temperature electrochemical sensor that is extremely
resistant to a variety of acid gases including carbon dioxide.
The front panel has an easy to read, 3-1/2 digit liquid crystal
display. Input power to the OXY-SEN is 115/230 VAC, 50-60
Hz or 24 VDC . The OXY-SEN can be wall/panel mounted or
used as a bench-top device.

The OXY-SEN was designed primarily for applications where
the user prefers to mount the gas diffusion end of the sensor
through a chamber, glove box, reactor, etc.

ELECTRICAL

Display: 3-1/2 digit liquid crystal

Input Power: 15/230 VAC, 50-60Hz or 24VDC

The diffusion end of the sensor has a threaded stock, pro­viding an easy and convenient way of installing the sensor
through the wall of a chamber, glove box, etc. by simply
drilling and tapping an appropriately sized hole. Ten feet of
coiled interconnecting sensor cable is supplied with each
OXY-SEN Oxygen Monitor. For gas tight integrity, the ex­tended-life sensor is equipped with an “O” ring that helps to
form a gas-tight seal. One advantage of using a threaded
sensor is that it eliminates the need to use sample pumps,
air driven aspirators, etc. to provide sample to the sensor.
An optional, ow through sensor housing is available for ap­plications where external sampling is required.
