The model A3 is a multi-sensor air quality monitor that tracks environmental parameters relevant both to outdoor and indoor use. For example temperature + pressure + humidity + CO2 + Formaldehyde + VOCs are important when discussing air quality in our homes, while temperature + pressure + humidity + ozone + Particulate Matter PM1/PM2.5/PM10 + Noise, are of huge importance for monitoring the general environmental quality outdoors (in our cities). There is no clear delimitation between the two categories and this makes the A3 an excellent tool to assert the air quality, given its many sensors and rich capabilities.
Installation and Protection from elements
When installed outdoors, the unit must be protected from rain, snow or direct sun exposure. We also recommend installing the “model A3” anywhere between 1 to 4 meter from ground level. The unit’s intake and exhaust ports are not water proof and so the unit is susceptible to water damage if installed unprotected. There are many solutions to this, and here are a few examples:
And here we’ve saved the best for the end. Any protection can be used, assuming two important requirements are met: 1) There is enough air flow across the uRADMonitor unit: this can be achieved with opposite sides openings like one on each side, or one on a side and one on a bottom . Also the size of the openings is important, the larger the better. 2) No water can get to the uRADMonitor unit.
This being said, a Stevenson shield is the best solution so far, and here is one used with A3 units in Israel:
