When Alphasense first began trading in 1996 the company’s focus was on delivering accurate, repeatable and cost-effective sensors for the monitoring and detection of gases in the safety sector. 26 years on, whilst sensors for Safety devices still represents a significant proportion of business, they are also seeing a welcome growth in demand for their air quality sensors, something which reflects rising and widespread concerns about the air we are all breathing day to day, rather than just those exposed to specific risks.
