General specifications

5 ms fast temperature measurements of hot
objects
Due to ratio principle insensitive to certain
dust and partially observed targets; in general
suppression of object emissivity changes
Rugged sensing head withstands 250°C without
cooling
Built-in laser marks the actual spot size at any
distance
Programmable 1 or 2 color mode
