LASCAR EL-WEM Indoor Air Quality Monitor
Product Information
The EL-WEM is a WiFi Indoor Air Quality Monitor designed to measure and monitor the air quality of indoor spaces. It measures four key parameters that affect indoor air quality – IAQ rating, humidity % RH, VOC index, and PM10 g/m3. The device has a sleek design and is easy to use. It comes with an Easylog feature that allows users to access their data anytime, anywhere.
Indoor Air Quality Monitor
This device measures the quality of the air around you, for your comfort and safety.
Please refer to the Quick Start Guide for information on setting up your EL- WEM.
IAQ Rating
The IAQ rating is a measure of the indoor air quality. The device provides
an IAQ score ranging from 1 to 18. An IAQ score of 18 or more indicates
excellent air quality, 16 or more indicates good air quality, 12 or more
indicates fair air quality, and 8 or more indicates poor air quality.
Humidity % RH
The device measures the relative humidity (RH) of the indoor space. The
recommended indoor humidity level is between 40% to 60%
RH. The device provides a humidity score ranging from 1 to 10. A humidity
score of 10 indicates RH less than 10% or greater than 90%, while a humidity
score of 1 indicates RH between 80% to 90%.
VOC Index
The device measures the Volatile Organic Compound (VOC) index, which is a
measure of the concentration of harmful chemicals in the indoor air. The VOC
index ranges from 1 to 201. A VOC index of less than 50 is considered safe,
while a VOC index of more than 200 is considered hazardous.
PM10 g/m3
The device measures the concentration of particulate matter (PM10) in the
indoor air. PM10 refers to particles that are 10 micrometers or smaller in
size. The device provides a PM10 score ranging from 1 to 5. A PM10 score of 5
indicates a PM10 concentration of more than 91 g/m3, while a PM10 score of 1
indicates a PM10 concentration of less than 33 g/m3.
Getting to Know Your Wem
Product Usage Instructions
To use the EL-WEM Indoor Air Quality Monitor, follow these steps:
- Turn on the device by pressing the power button located on the top of the device.
- The device will automatically start measuring and displaying the IAQ rating, humidity % RH, VOC index, and PM10 g/m3 on the screen.
- To view the data log, connect the device to a WiFi network and download the Easylog app on your smartphone or tablet.
- The app will display the data log and provide insights into the air quality of your indoor space.
- To improve the air quality of your indoor space, take appropriate actions based on the readings provided by the device.
For example, if the IAQ score is poor, increase ventilation or use an air purifier to reduce the concentration of harmful chemicals in the air.
Easy Cloud
It only takes a few moments to connect your EL-WEM to the Easylog Cloud, giving you control over your device and access to your data from any internet- connected mobile device or computer.
What Contributes to Indoor Air Quality
Air quality is a key contributor to feeling comfortable, and staying healthy, at work and in home. The EL-WEM uses a silent fan to sample the air around it, the internal sensors measuring five important factors.
Particulate Matter (PM)
Tiny particles that hang in the air include pollen, dust, mould spores and
soot from engines and fires. In high concentrations, these can cause allergic
reactions and health problems. The EL-WEM measures two types: PMIO and
extremely small PM2.5.
Temperature
Our bodies immediately sense if we are too hot or too cold, but temperature
changes can also cause physical reactions that affect our susceptibility to
viruses and other airborne diseases. Poor temperatures can also accelerate the
growth of mould and bacteria on indoor surfaces.
Humidity
The amount of moisture in the air can affect how well our bodies can maintain
a comfortable internal temperature. Low levels can read to irritated skin and
eyes, and high humidity can stimulate mold growth. Volatile Organic Compounds
(VOC’s) VOCs are gases and chemicals in the air that can have health effects.
Many common chemicals and materials emit VOC’s, sometimes over long periods of
time. These include paint and varnishes, cleaning products and air fresheners,
plastics, fabrics and many more.
Air Pressure
High atmospheric pressure can exacerbate joint pain and contribute to
headaches and migraines. It can also have an effect on blood pressure and
blood sugar levels.
How can I improve air quality
You can check to see the measurements taken by your EL-WEM on the EasyLog
Cloud website or App. The readings are colour coded so you can see exactly
which
parameters are best and worst. Readings marked orange or red are ones where
you should take action to improve your air quality.
Temperature
If you have a heating or cooling system in your room, you should check the set
temperature. Bear in mind the number of people using an indoor space can
change the amount of heating or cooling needed. Opening or closing windows and
doors, to encourage or prevent draughts, can also be an important step to
take.
Humidity
Air conditioning systems and dehumidifiers are an excellent way to keep
humidity at comfortable levels. Remember that humidity levels are often set by
local atmospheric conditions so opening or closing windows and ventilators can
also help control humidity.
Particulate Matter
Particulates will always have a specific source, so you should try to un-
derstand where these are coming from in order to control them. They are often
in the form of soot created by combustion, so be aware of road traffic,
outdoor fires and burning, and indoor fires, stoves and boilers. Particulates
can also come from pollen, dust and mould spores, all of which also cause
allergies, so it’s important to keep your indoor spaces clean, and free from
the damp conditions that can accelerate mould growth.
Volatile Organic Compounds (VOCs)
Like particulates, there will always be a specific source or sources of VOCs,
and unfortunately, these can often be everyday materials we have in homes and
workplaces. These can include paint, varnishes and solvents, cleaning products
and disinfectants, air fresheners, plastics, fabrics, inks and adhesives.As
far as possible they should be stored in closed cupboards or containers away
from the busiest indoor areas. You should also encourage air circulation by
opening windows and internal doors, and using fans and ventilators where
available.
IAQ Rating Index
Indoor Air Quality is scored out of 20, by adding together scores for four
measured parameters. The total score determines the IAQ
rating, on five levels, from Excellent down to Inadequate. The status ring
color on your EL-WEM matches the IAQ rating.
IAQ Rating| Excellent| Good| Fair| Poor|
Inadequate
---|---|---|---|---|---
IAQ Score| 18 or more| 16 or more| 12 or more| 8 or more| Less than 8
The IAQ score is calculated as follows:
Example: Temperature 10 oc (1 point), Humidity 9% (1 point), VOC 220 (1
point), PMIO 96 (1 point) = 4 points total, IAQ rating is Inadequate.
You can find a copy of this table, including Temperature in OF, by clicking
theo help icon next to the measurement readings in the EasyLog Cloud.
Do Not Disturb Mode
Your WEM contains an alarm sounder that you can activate from the EasyLog
Cloud, to give an audible warning if the IAQ level is Poor or Inadequate.
There is also an option to set a time period each day when the status ring and
sounder are inactive. Back-up Battery
The EL-WEM contains a back-up battery that can power the unit if mains
power is lost.
The battery is intended as an emergency backup only and should not be used to
power your EL-WEM for long periods.
The battery cannot be accessed or changed by the user and is recharged
automatically when mains power is restored. After you’ve connected the EL-WEM
to your WiFi network, if the power button starts flashing it means the monitor
has been unable to connect to the network to upload data. The EL-WEM will
automatically try to reconnect, but you should also check if your WiFi network
is available. If you want to perform an immediate upload to the Cloud and your
network is available, do a short press of the power button. This will create
an audit mark in the event record. To reconfigure the WiFi settings (e.g. to
change your EL-WEM to use a different WiFi network), press the Setup button on
the base of the unit for 4 seconds.
Also available: High Accuracy EL•WEM+
The EL-WEM+ monitors two additional parameters for even more
accurate Indoor Air Quality measurements:
- Carbon Dioxide key indicator of air circulation and freshness
- PMI particulates, the smallest and most damaging class of particle pollution
