Contactless Thermometer  Are you running an infrared
temperature?  Published in issue 2/2011 on page 48  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.     Resistors (0.25W 5%)
