Carlow-based Xenon has secured €1m in funding for the company's handsfree, infrared temperature testing device called Fever Defence.
The investment was made by New York based venture capitalists Antonio Ruiz-Gimenez and Kerry Propper.
Xenon's Fever Defence is a standalone device that uses a thermal imaging camera and facial detection camera to test people's temperature as they enter a building or a site.
The non-contact device measures skin temperature in less than one second, and is accurate up to about 0.3°C.
When the temperature is read, the device then alerts the individual of the result using a red and green light stop-go system and an audible notification if a potential fever temperature is detected.
Paddy Byrne, Managing Director of Xenon Fever Defence, said the new investment will help the company to scale up its operations across Europe and the US.
"Employers are moving quickly to put additional safety measures in place to protect their workplaces and their customers against the risk of Covid-19," Mr Byrne said.
"Our devices have been installed at companies and organisations across a number of different industries - from construction sites and offices to retail and childcare settings in the Irish, European and US markets," he added.
