Hone Global is developing a range of digital hand-held lab devices that collect complex light signals using a patented spectrometer (sensor array) from any food sample placed inside it. These light signals are then decoded using a proprietary industry leading machine learning software to deliver lab test results on food products, in real-time, to the user’s mobile phone.
