Icohup aims to develop competitive pollution measurement instruments. The goal is to spread these technologies to consumers and to deploy pollution measurement networks with professionals. We are focused on providing sensors capable of detecting any type of pollution in your environment ! Our first sensor Rium is different from current radioactivity sensors like Geiger counters, dosimeters or radiometers. In addition to its high sensitivity, RIUM is able to provide information such as radioisotopes identification or X-ray spectrum. This process is now achievable thanks to our patents based on scintillation spectrometry technology. As a connected object, Rium can be deployed throught fixed or mobile network for industrial monitoring, smartcities supervision, on drones and many more situations. Rium combines high performances, a competitive price and a small size.
