Most commercial instruments available are designed, tested and
calibrated for general industry use, and as such are often unsuitable
for the harsh conditions in glove boxes where metallic and corrosive
materials are often found, and accurate measurement of the gas quality
is required at the bottom end of the scale. Glove Box Technology
Limited design and manufacture a range of three oxygen analysers
specifically for inert gas glove boxes.
Portable Oxygen Analyser
Model O2-A
The same technology has been enclosed in a compact unit for
in-glove box use O2-A, which makes it quick and easy to install,
and being portable, can be used in a number of glove boxes.
Operating off mains or self-contained battery, this unit is
alarm set for 10 ppm and has a digital display measuring the
higher range in percentage mode and the lower range in ppm. |
Integrated Oxygen
Analyser Model O2-B
Our in-built glove box oxygen analyser O2-B displays the oxygen
level in graphic bar form on a touch screen in colour, and is
auto ranging showing 0 to 10 ppm in green, 10 to 100 ppm in
yellow and 100 to 1000 ppm in red. Alarms are user set in the
menu of routines.
Historical data of oxygen is graphically presented over time
in two menu routines with time defined in 7 hours in graph A,
and 7 days in graph B. Additionally data can be downloaded to
a computer, and no volt contacts are available for remote alarm
initiation. |

Model 02-C-2
|
Free Standing Oxygen Analyser Models
O2-C-1 & O2-C-2
A freestanding glove box oxygen analyser model O2-C-1 designed
for plumbing into existing glove box or similar equipment/apparatus.
Model O2-C-2 will measure two glove boxes, alternating by use
of a change over switch. Both units are alarm set for 10 ppm.
The freestanding units have a digital display, and measure the
higher range in percentage mode and the lower range in ppm.
The units are mains power operated. |
Common to all oxygen analysers is the works calibration which is
carried out at 0 ppm and 5 ppm using certified calibration gas,
this being the mid-span of the usual 0 to 10 ppm range between ideal
operation conditions and alarm. Accuracy is +/- 1% and repeatability
is 0.5%.
