Introduction2
HS4000 is an ultralight and highly sensitive instrument that utilizes infrared laser to remotely detect methane leaks. HS4000 comes with
Bluetooth capability that can transfer measurement data in real-time to the dedicated APP. Users can use the APP to check, record and
export the data. Through the APP, users can generate detection reports using the saved data as well.
2.1
Working Principle
HS4000 emits an infrared laser at 1.65 um. The laser beam travels to the target, is partially absorbed by the gas, then reflected all the way
back into the receiver.
The reflected laser is collected and converted to an electrical signal that carries information needed to deduce the relative methane concentration.
The reading is expressed by a methane column density (ppm*m). It is the integral of the methane concentration (ppm) and the distance (m)
on the optical path.

Instructions on the red dot sight
Users can look through the red dot sight to achieve better aiming. The red dot sight is powered by the device . It automatically lights up after
powering on the device.
NOTE The sight is effective when aiming over 15 m away. If the distance from the measured object is too short, the red dot will not overlap
with the green indication laser.
Figure 4.5 Red dot sight diagram
If the red dot and the green indicator laser do not overlap when aiming for a long distance (>15 m), the red dot calibration can be performed
by adjusting the knob on the sight.
-15-
If the red dot is higher than the green indication laser, turn the
knob counterclockwise to make it lower; if the red dot is lower
than the green indication laser, turn the knob clockwise to move
it up.
If the red dot is to the right of the green indication laser, turn
the knob counterclockwise to shift it to the left; if the red dot is
to the left of the green indication laser, turn the knob clockwise
to shift it to the right.

4.6
Detection Do's and Don'ts
4.6.1
Case 1
When detecting through the glass, if the infrared laser is incident on the glass vertically, part of the light reflected by the glass will be
received by the device, which will cause light intensity saturation or inaccurate measurement result.
In such case, please point as shown in Figure 4.6.B to avoid receiving the glass reflected light.
4.6.2 Case 2
Please avoid detecting through materials that have
strong absorption or reflection effect on the infrared
laser, such as PMMA, laminated glass, anti-infrared
glass. In such case, the methane concentration behind
can't be detected or the measurement result may be
inaccurate.
A B
Figure 4.6 Do's and Don'ts when detecting through the glass
Figure 4.7 Avoid detecting through anti-infrared or absorbing infrared material
-19-
4.6.3 Case 3
When detecting towards the corner (or similar situation), as shown in Figure 4.8.A, the infrared laser may reflect between walls, resulting
in high measurement concentration. In such case, please point as shown in Figure 4.8.B to have the accurate measurement result.
