The Mirus Weatherproof Kit is the perfect solution for taking accurate, continuous environmental noise readings over a period of time without having to worry about moving the kit and distorting some of the measurements. It's strong housing means that it is capable of being left outside without recieving any damage to the class 1 noise analyser housed inside. If you need a collection of environmental noise data over a long period of time this is then kit for you, the option of a longer battery life means you can continue to take your measurements for longer than ever before!
