OMEGA’s OS418-LS is theultimate tool for temperaturemeasurement. Accurately verifysurface temperatures with twoof the most reliable temperaturesensors:
• Non-contact micro-machinedthermopile
• Type K thermocouple socket(free T/C included)
Such an arrangement can fulfillmost temperature measurementrequirements. The non-contactinfrared measurement is ideal fornon-reachable situations, due tosafety or sanitary reasons—instantreadings, safely and reliably.Or use the thermocouple for highprecision measurement of contactsurfaces, gases, and liquids.The OS418-LS can also helpmeasure emissivity, which is oftendifficult for a user to determine.Use the Type K thermocouplecontact to measure the truetemperature. Then, use the non-contactinfrared to get the surfacetemperature. Adjust the emissivityuntil they are the same, with theoption to use the same emissivitysetting for that object next time.No more guess work, no morelooking up on Emissivity Table.This unit also comes with anultra-long battery life (batteries are included).

What is the maximum distance you can get a temperature?

Asked by: Rob123
It depends on the dimensions of what you are measuring. In this case, if the item is 1 inch wide, then you would have a maximum distance of 12 inches. Hence, the field of view is 12:1 ratio. (As long as you fill the field of view).
