Do not shine the laser onto eyes or skin.
Do not test black, brown or dark-colored substances. When these
substances absorb the energy of the laser, they can become hot or start to
burn, resulting in fire.
Do not place the substance to be identified on paper for testing. The
paper may absorb the energy of the laser and become too hot or even start
to burn, resulting in fire.
If the substance to be identified is light in color, any dark spots in the
substance absorb the energy of the laser more easily and quickly heat up.
If you have not determined if the substance to be identified has heat sensitive
properties, prepare in the following way:
•
Place a small amount of the substance to be identified (<300µl or 5 drops for
liquids, <300mg for solids) into a reagent bottle or bag.
•
Do not seal the container.
•
Do not place the substance to be identified on paper or other cellulose materials
for testing.
•
Set a detection countdown.
•
Reduce the laser power to a low level.
•
The safe use zone for this device is 50cm.
•
Keep the laser emitter window at least an arm's length from people's eyes.
Online detection
If the device is logged in to a cloud detection service account, online detection can be
carried out while connected to a network. When carrying out online detection, the
device calls the cloud database to compare substances and return results.
1. In the detection domain, tap Analysis.
2. If the sample to be identified could be a flammable or explosive substance, when
setting the detection countdown, the length of the countdown should depend on
the time it takes people to move a suitable distance away. When a countdown is
not necessary or a countdown has been set, line the laser emitter window up with
the substance to be identified or its container, and then tap Analysis.
3. After the required time (the detection time depends on the nature of the sample),
the device shows one of the following types of results.
