Your PurgEye®300 Plus Weld Purge Monitor®is an instrument
to read from 0.1% (1000 ppm) down to 0.0001% (1 ppm) oxygen.
Your PurgEye®300 Plus Weld Purge Monitor®delivery and
storage box contains:
By following the instructions about how to use your PurgEye®300
Plus, you will become quickly familiar with its operation and there
should be no trial and error involved.
1. Familiarise yourself with this manual and the PurgEye®300
Plus controls.
2. Switch on the PurgEye®300 Plus. See item 3 below. Continue
to learn the controls.
3. Connect the green tubing to the white connector at the rear
of the instrument. The other end of the green tubing, with the
lter unit, should be attached to the exit hose of the product
that you are purging, so that the exiting gas can pass through
the lter and then into the monitor housing and internal sensor
to be measured.
WARNING: The monitor should not be connected directly to a high
pressure, unregulated cylinder.
GETTING STARTED
• The PurgEye®300 Plus Weld Purge Monitor®.
• 150 mm long red tube to attach to red purge exhaust.
• 1 metre long green tube with lter.
• Mains lead with psu (power supply adaptor) and plug package
to suit 110-250V, 50/60hz AC supply for all countries.
• This User Instruction Manual.
• PurgeNet™ head for connecting to PC for PurgeLog™ or
accessories.

GETTING STARTED continued
4. Use the short length (150 mm) of red hose provided to attach
to the red purge gas outlet at the rear of the monitor. (This is
important and it is intended to prevent air with oxygen migrating
back into the monitor through the exhaust and distorting the
readings).
5. Wait for the sensor to warm up, shown on the display by saying
“please wait”.
6. Set your inert gas regulator for an outlet pressure of 0.5 bar and
a ow rate of 7-10 litres/minute. When purging at higher ow
rates, ensure that there is another exhaust outlet available so
that all of the exhaust gas doesn’t come through the monitor.

PurgeNet™
The PurgEye®300 Plus Weld Purge Monitor® is tted with a 3-pin
PurgNet™ connector at the rear as indicated on page 5. This connector
is used to connect the PurgeNet™ lead which in turn enables the user
to connect smart accessories and access the PurgeLog™ software.
Software and trafc light warning accessory already available
and other accessories to be released from development in 2018.
Quick Fit sample gas tube fittings
Where both sample gas tube ttings are used, the exhaust tting
is identied by a red release ring. The tube connecting the purge
gas being sampled should be connected to the other tting (white).
NOTE: The Quick Fit ttings and the lter can only be used with
the special tubing supplied with the monitor. Do not attempt to use
other tubing. Contact HFT®if spare tubing is required.

below the alarm set-point) then the mute feature is automatically
disabled, allowing the sounder to activate next time the alarm is
activated by a reading above the alarm set-point value.
Display
Holding the toggle button will change the display units from either
ppm or %, pressing the display button will cycle the display through
the various menu options. By default these are as follows:
Current oxygen sensor reading.

Zirconium Oxide Sensor Care
As a general guideline, the gases to be measured should be free
from dust, organic vapours, condensation and products capable of
condensing. Such components can block the gas conduits in the
sensor and cause permanent damage.
There are processes where gases that contain certain components
form solid or liquid condensation when the temperature falls below a
certain value. This condensation can be deposited in the gas conduits
to the sensor and either affects the measurement or damages the
sensor. These components should be identied and removed before
commencing a measurement.
It is important that the material to be welded is clean, dry and free
from grease and other contaminants.
Keep welding enclosures clean and clear of non-essential items that
could out-gas when hot.
Please Note: Permanent damage to the sensor can occur due to
the following circumstances:
• Physical shock.
• Water vapour, condensation etc. use water lter.
• Sensor is in the unheated state in gas which contains H2S or SO2.
• Contact with gases which contain halogens like F, Cl, Br.
(Fluorine, Chlorine, Bromine) For example: CFC’s, CFW, agents
and solvents.
• Contact with organic vapours for example: agents and solvents,
oil mist, petrol vapour, contact sprays, cleaning sprays, corrosion
protection sprays.
• Also damaging are volatile organic substances. For example:
vapours of silicone like sealing compounds, adhesives and
greases.
• Use of silicone tubing.
Damage to the sensor due to contamination or condensation is not
covered by any warranty.
CARE and MAINTENANCE

PAGE 12
Filter:
If the sample gas ow rate is reduced too much due to an old clogged
lter then the ow warning (ashing arrow) will be displayed.
Filters should only be replaced with the correct type. The in-line
lter MUST ALWAYS be used, or your PurgEye®may read incorrectly
and/ or be permanently damaged.
Spare lters available from your HFT®Distributor.
Calibration:
HFT®has a number of calibration facilities internationally. Contact
your nearest HFT®Distributor who can tell you about your closest
one. We recommend an annual calibration.
Testing gas source:
As well as its use as a Weld Purge Monitor®the PurgEye® 300 Plus
can be used to test the quality of your purge gas supply.
Ensure that a regulator is connected to the gas supply and that it is
set to 0.5 bar. Set the ow rate to 1.5 litres/min and connect the
PurgEye® monitor to the gas ow using a suitable tube.
Quick Fit tube connections:
These ttings are leak tight and pressure tight. They are designed
to take 6mm OD Polyurethane tube.
