Mounting, except RHT-out
Select the installation location so that air can flow freely on all sides of the
transmitter, representing the air that is to be measured. Avoid heat sources
and direct sunlight. Mount the device to the measuring location with one
of the following ways:
• Simply place the DUST40, DUST13, KOMBI-DP or RHT-in on any surface
with the bottom facing down.
• First mount the separate wall holder with two universal countersunk
screws (ST 2.5 or ST 3.0). Use applicable length and type of screws
depending on wall material. In the correct orientation, the wall holder has
its hooks pointing upwards. Attach the DUST40, DUST13, KOMBI-DP or
RHT-in to the holder.
Mounting RHT-out
This model can be mounted using any of the mounting screw holes in the fixed mounting flanges of the enclosure. Always
make sure to mount the device in vertical orientation so that the ventilation holes in the bottom of the enclosure point
downwards ensuring that water or any other liquids cannot enter through the ventilation holes. Ingress protection class
IP42 can only be attained in the correct vertical mounting orientation.
Mounting KOMBI-DP
Mount as instructed above and then attach the pressure hoses to the two black hose connectors at the bottom of the
device. The device measures the pressure dierence between the two hose connector ports. Use only flexible plastic hose
with inner diameter of 4 mm / 0.15 in. When routing and installing the hose, make sure the hose does not get pinched or
blocked. Always minimize the length of the pressure hoses. The maximum recommended pressure hose length is 1 m /
1.09 yd to attain the specified measuring accuracy.
The other hose connector port can and typically will be le without a hose connected to it.
Power supplies
DUST40, DUST13, KOMBI-DP and RHT-in indicates a power-up by blinking the led next to the micro USB socket.
KOMBI-DP, RHT-in, RHT-out variants
These variants are powered with 3 pcs LR6 batteries (AA 1.5 V alkaline). High quality batteries should be used, for example
Energizer EN91.
The device is supplied with batteries already installed, so it is ready to be used.
DUST40, DUST13, KOMBI-DP, RHT-in and RHT-out can alternatively be powered with an external supply. When an external
power supply is used, the batteries can be omitted or used as a backup supply. Use the micro-USB socket to connect an
external supply to the device.
DUST40 and DUST13 variants
These variants with PM sensor must be powered with an external supply. Use the micro-USB socket to connect an external
supply to the device. 3

Operation
Aer the DUST40, DUST13, KOMBI-DP, RHT-in or RHT-out is successfully installed, it operates on its own. However, there are
some considerations that are good to know when using the DUST40, DUST13, KOMBI-DP, RHT-in or RHT-out devices.
RHT measurement
Temperature is given in °C. Humidity is given in %RH. The eGate cloud platform can convert the readings to °F as necessary.
dP measurement
The pressure dierence between the outlets is measured using the air flow. The direction of the air flow determines the sign
of the reading. If the outlet in the le-hand side is in higher pressure than the outlet in the right-hand side, the reading is
positive and vice versa. The pressure dierence is given in Pa.
Particle measurement
A small fan sucks air from the opening in the cover. Inside the device the air
passes through a laser beam. The particles will cause a flash when passing the
laser, allowing them to be counted and their sizes (diameter) estimated.
The mass of the particles is estimated by assuming that they have a density of
1.65 g/ml and making assumptions of their shape. The result is not accurate if
the density, shape, or refractive index deviates significantly from the estimates
used in the calibration.
DUST13 sensor variants measure PM1, PM2.5 and PM10. The larger DUST40
sensor measures PM1, PM2.5, PM10 and PM40.
The sensor does not need periodic recalibration. If it appears to have dust deposited inside, compressed air can be used
with extreme care to blow it clean.

Maintenance
Checking the status
Press the button to check the status of the eGate-Kombi-LWUS. The led located next to the micro USB socket will indicate
the status:
• If the led blinks green, everything is fine, and the remaining battery capacity is estimated to be over 20%.
• If the led blinks red, the remaining battery capacity is estimated to be below 20%.
• If the led does not blink at all, the device isn’t working properly
Replacing the batteries
Replace the batteries by following these steps:
• -RHT-IP42 model: Remove the four screws holding the outer enclosure cover in place.
• Remove the device from the holder by pushing it upwards.
• Remove the two PZ1 screws and open the cover.
• Replace the batteries with 3 new LR6 (alkaline AA) batteries observing the polarity. Avoid touching the electronics.
• Reassemble the device.
Cleaning
If there is visible dust inside the device, blow it away with pressurized air while avoiding too strong pressure. The enclosure
exterior can be wiped with a damp cloth, but no drop of liquid must enter the device.
