Set-up and Installation:
Unpack the device and make sure all the accessories are present, then follow these instructions.
Step 1: Charging the battery. Plug the micro-USB end of the charging cable into the micro-USB port
on the side of the device then connect the other end to the USB port of a power source (computer,
mains adapter, etc.).
The display lights up and the battery charge level bar shows charging progress (1). A red power-on
LED comes on at the top of the tester. Once the battery is completely charged, the charge level
indicator stops blinking and the power-on LED turns green. Disconnect the cable. The battery charge
life is 4 hours.
The device needs 200 seconds to warm up and adapt to the atmosphere. A countdown of this time in
seconds is shown on the TVOC display line (4). To recover from the effects of packaging and
shipping, the device must be placed outdoors in a dry, protected area for 30 minutes in order to clear
the sensors before first use.
Important: Do not make any adjustments during the warm-up period.
Unfold the stand and position the air quality tester in a convenient place in the room, office,
warehouse, etc. Choose a location where the sensor air vents on the front and back of the device are
completely unobstructed; this will ensure the device functions properly. Keep the device well away
from any direct source of pollution as well as any liquids, heat sources, flammable products, and
magnetic fields. The measurements made are shown on the display.
The tester makes a slight noise during use. This is normal and is caused by the sensor cooling fan.
The noise stops when the tester is turned off.
Important: if the screen becomes dim and/or the battery charge level bar (1) starts blinking,
it means the charge is running low. Recharge the battery fully.
To turn the tester on or off, press and hold in button (7).

visualize the trend of the automatically measured readings. The tester lets you display ten readings
every ten minutes. The maximum observed value of the pollutant is shown at the top of the screen.
Important: Readings can only take place when the air quality tester is switched on. If no readings are
displayed, make sure the (Clear Log) option is not activated (Clean).
Step 4: Measurements and comfort ratings
1. Particulates are airborne particles resulting from wood burning, farming activities, general
dust, etc.
Three sizes of “particulate matter” (PM) are defined: PM1.0, PM2.5, and PM10, representing particle
diameters of less than 1µm, 2.5μm, and 10µm respectively. PM2.5—“fine particles”—are the most
common in indoor air.
The measured level of PM2.5 fine particles is displayed by default on line (2) of the interface.
Colour band
Range of PM2.5 values
Rating
Green 0–75 µg/m³ Good
Yellow 76–300 µg/m³ Modest
Red 301–999 µg/m³ Bad (danger)
Important: Different counties stipulate different legal or recommended thresholds for fine particles.
These thresholds focus mainly on PM2.5. The World Health Organization has defined exposure
thresholds for PM2.5 and PM10 particulates, but PM1.0 is generally overlooked when it comes to
exposure thresholds and guide values. Nonetheless, PM1.0 is the most harmful category of the three,
their extreme smallness allowing them to penetrate the human anatomy. That’s why the Quaelis
indoor air quality tester includes this category in its measurements, especially for the more sensitive
among us. We therefore recommend that PM1.0 measurements be monitored to ensure they remain
lower than those of PM2.5.

TVOC Rating RECOMMENDATIONS
Green 0–0.600 mg/m³ Good Continue airing the room regularly to renew the
air.
Yellow 0.601–1.000 mg/m³ Modest Air the room; leave the room for now.
Limit heating during winter.
Red 1.001–5.0 mg/m³ Bad
(danger)
Air the room and leave it.
Install a permanent ventilation system.
Identify and reduce all sources of possible
pollution (furniture, ceiling, floor and wall
coverings, home improvement work, painting,
etc.).
The values detected by the tester at a given moment can often be higher than the exposure threshold.
That’s why each threshold is coupled to a specific exposure time. If the measured values regularly
exceed these limits, a professional diagnosis is advisable to identify the source of the pollutants.
The AQI (Air Quality Index) uses coloured bands for easy interpretation of the air quality:
Green: 0-75 The air quality is good (Good)
Yellow: 76-150 The air quality is tolerable (Slight)
Red: 151-300 The air quality is poor (Moderate)
Purple: 301-500 The air quality is critical (Serious).
Reminder:
Pollutant-related risks vary with exposure levels (mild to extreme).
Formaldehyde: Tiredness, headaches, sleeplessness, skin and eye irritation, allergies, eczema,
breathing difficulties, etc.
Fine particles PM2.5: Breathing discomfort, nasal and bronchial irritation, other signs of irritation, etc.
That’s why it’s important to measure indoor airborne concentrations, which are important criteria when
drawing up room air-change regulations.
Important: the short-term actions above are intended only as a guide. They cannot be considered a
substitute for legislative or regulatory provisions or any other obligation that may exist. More specific
actions may need implementing. The values detected by the tester at a given moment can often be
higher than the exposure threshold. That’s why each threshold is coupled to a specific exposure time.
If the measured values regularly exceed these limits, a professional diagnosis is advisable to identify
the source of the pollutants. In the case of public buildings and venues, seek expert advice from the
relevant authorities, e.g., Regional Health Board or equivalent, Regional Environmental Office, etc.
