2 Channel Type K/J - 800007
Thermocouple thermometers measure temperature at the thermocouple and are
therefore useful in measuring "cold spots". It does take a few seconds
for the mass of the thermocouple to reach equilibrium with the surrounding air
but not too long.
Laser aimed Infra-Red thermometer
These measure temperature all the way from the sensor to the surface of the
object they are aimed at.
