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:

  1. Turn on the device by pressing the power button located on the top of the device.
  2. The device will automatically start measuring and displaying the IAQ rating, humidity % RH, VOC index, and PM10 g/m3 on the screen.
  3. To view the data log, connect the device to a WiFi network and download the Easylog app on your smartphone or tablet.
  4. The app will display the data log and provide insights into the air quality of your indoor space.
  5. 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. LASCAR EL-WEM Indoor Air Quality

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.LASCAR EL-WEM Indoor Air

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:

LASCAR EL-WEM Indoor Air Quality Monitor fig-10

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
