NASA Turf Stress Detection Glasses
TSDG1-N Instructions
NASA space technology has given you the ability to spot stressed turf close up or at a distance...
with plenty of time to react to correct any unhealthy conditions. With these new Turf Stress
Detection Glasses, you can spot problem areas on your grass before they become visually
apparent. By spotting turf that is under stress early allows you to diagnose problems early by
saving time and money.
Set comes with three lenses - Purple = Stress Detection Lens
Brown = Sunglass Lens & Yellow = Night Vision Lens
Simply put the stress detection glasses on and the
NASA Technology blocks out all the green
coloring from the field of view. Any stress or
change in plant health will appear as a different
color then the surrounding plants. If you look at
any area of like plants, whether it is grass, trees,
plants or shrubs, any difference can be quickly
noticed. After the color change is notices further
inspection can be made to determine what is the
cause of the stress.
Additional diagnostic tools like Moisture Sensors,
Infrared thermometers and soil thermometers can
also be useful in determining the cause of the plant
stress.
Instructions
1. Hold the frame near the temple and gently
pull the lens out of the frame channel..it
will “Snap “ out of the fastener. Slide your
fingers holding the frame to the middle of
the frame and continue to pull on the lens.
Keep pulling and the lens will “snap” out
of all three fasteners. The frame fasteners
fit into the three indentations near the top
of the lens to hold the lenses securely in
the frame channel.
2. Snap the new lens into the channel by
pushing the new lens and frame together.
It is easiest to line up the center lens
indentation with the center frame fastener
first (a plastic catch that fits into the lens
indentation) and then snap in the two lens
sides into the frame.
3. Gently remove the nose piece by
squeezing the bottom sides together and
gently remove it from the lens. Install the
nose piece into the new lens by gently
pushing it onto the new lens…the grove in the nose piece fits onto the lens and is held in
place by the shape of the lens. Use the micro-cleaning cloth to remove any fingerprints.
