Contactless Thermometer

Are you running an infrared temperature?

Published in issue 410, February 2011

This thermometer measures at the same time both the ambient temperature and the temperature of any object placed within its ‘field of view’. And even though the ambient temperature range ‘only’ goes from −40 to +125 °C, the object temperature can be from −70 to +380 °C, and all with an accuracy of 0.5 °C and a measurement resolution of 0.02 °C.
