The Gratnells Learnometer is designed in conjunction with Professor Stephen Heppell and his research team and is designed specifically for education. The Learnometer enables you to comprehensively monitor your learning environment and work out how to improve learning outcomes.  It tracks the seven key factors that determine air quality: temperature, humidity, light, sound levels, carbon dioxide (CO2), chemicals (VOCs), and dust (PM2.5). It has a touch sensitive and fully customizable display, with an 8-hour battery backup. It can be used to constantly monitor your air quality, and connects to your wireless network so it can be managed remotely.



In October 2020 the Learnometer won the prestigious Worlddidac education award, and in 2021 has been shortlisted for a BETT 2021 Digital Device Award.
