Win3 Portable particulate monitor dust instrument

More and more miners pay their attention to the Pneumoconiosis and they expect some tools to bring them a more heathy operation enviroment and they made efforts to reduce their dust exposure. Their efforts included: changing where they positioned themselves, making ventilation system improvements, and using respirators more often. 

Win3 Dust Measuring Instrument is a very compact/light weight moitoring instrument that real time measures dust and particulate continuously including PM10, PM2.5, PM1 etc, which can infom and alert the miners when dust levels exceed regulatory limits.
