Yes, the Laser Egg is portable! It is approximately the size of your palm and is lightweight, perfect for if you wanted to take it on road trips, to the gym or in the car.
It also performs very well outside, and it is being used in a number of locations around the globe to measure local outdoor air quality. That said, it has not been designed as an “outdoor monitor” and thus it is not waterproof or weather-proof. If you do use it outdoors, it’s very important that it is placed in a protected environment, where the elements cannot cause damage to the device, and treated with care, to not damage the sensors inside.
