The OS-610 and OS-620 Series 
pyrometers from OMEGA contain a 
passive sensor which receives and 
measures (heat) radiation from an 
object. Since temperature is 
measured without contact, 
measurements are made rapidly 
(one second) so that thermal 
patterns and transient phenomena 
can be observed. Since heat is not 
removed from the measured object, 
accuracy is assured. Moving 
objects, dangerous materials and 
electrical components can be safely 
measured.
The OS-620 Series infrared energy 
meters have the additional feature 
of measuring heat loss (or gain) 
through walls and windows without

physical contact. These versatile 
units are designed to measure the 
temperature of building materials 
such as paper, plaster, ceramic, 
stone, concrete and glass that have 
emissivities between 0.9 and 1.0.
Net heat flow is measured inside the 
building by switching the instrument 
to BTU (or watts) and aiming at a 
wall or surface which represents the 
internal temperature of the building. 
The display is then “zeroed,” using 
the zero adjust control. Net heat 
flow in BTU (or watts) is then 
displayed when the instrument is 
aimed at an exterior wall or window.
