Safety Issues
Caution: The infrared and red laser output from the GasFinder3-OP have very low
power (conforms to Class 1 as per IEC 60825-1) and will not damage eye tissue.
However, it is the recommendation of Boreal Laser Inc. that, as with ANY
LASER SYSTEM, the user/ operator should avoid staring directly into the
output aperture of the instrument.
Note that the laser beam is infra-red and is not visible to the eye.
Sequence of the Installation:
The preferred sequence is to install the retro refl ector fi rst and then the GasFinder2 . This
ensures that when the GasFinder2 is mounted, it can be aligned at the same time.
Portable use
Retrorefl ectors (Retros)
The retrorefl ector is a vital part of the system and choosing the correct one
is necessary for the correct operation of the system. Refer to pages 3.3
and 3.4 for details on choosing a retro. For short paths where refl ective
tape is used, the tape can be attached to the back of an enclosure
which is fi tted to a tripod or placed on a wall in any convenient location.
The angle of the tape can be adjusted to give an adequate signal return
provided this does not degrade the R
2
.
Where retro s are used on longer paths, these may be mounted in
an enclosure on a tripod, or the enclosure placed in any convenient
location.
If ppmm is to be displayed, the
GasFinder2 does not require any changes
when different path lengths are measured; the only change is to use a different retro to ensure
the correct value for the light.

Setting up the Tripod
1. Holding the tripod vertically, free of the ground, press the
red lever (a) just under the head. This frees the brake on
the leg and allows it to extend. Do this for each leg in turn.
Alternatively, pressing levers (b) will allow all three legs to
come down at once. If the extension is not enough, the lower
portion of the legs can be extended by loosening the collar.
Spread the legs.
2. Position the tripod fi rmly on the ground with the height adjusted to be about level with the
operator’s chest.
On some surfaces the rubber feet should be screwed in to expose the pointed steel pin
which aids in gripping .
3. When the correct height is reached, tighten the screws on the three braces.
