Product Description

RAMP is a reliable, portable, and affordable air quality monitoring system that can detect up to five gaseous chemical pollutants, as well as temperature, humidity, particle matter, and weather conditions in a variety of situations. For remote, worry-free operation, the unit has straightforward deployment choices and optional solar charging. RAMP’s dependability has been demonstrated in 16 nations, including the US, in applications for local government, building, the environment, and academia. For CO, NO, NO2 O3, and SO2 gases, electrochemical sensors offer PPB, or parts per billion, resolution. The platform is portable and has a long battery life. To provide a flexible and reliable air monitoring platform that meets your demands, a PM2.5/PM10 particulate matter sensor and internal SD storage are also included inside a durable and strong casing.
