Testo 845 Far Field and Close Focus IR Thermometer

E23-91 

   

The Testo 845 IR thermometer enables the accurate measurement of surface temperatures with smallest diameters at short and long distances through the 
use of switchable far-field and close focus optics. A cross laser marks the measurement point exactly and, at a distance of 1.2 metres from the object, the 
measurement point diameter is only 16 mm whilst at 70mm, the measurement point diameter is only 1 mm. 

Key feature and benefits include:

 



Switchable optics for far-field and close focus with bright cross laser sighting to identify measuring point

 



Accuracy ± 0.75 °C with 100ms measurement technololgy

 



Backlit display (3-line) showing °C, min./max. values, alarm limit values and degree of emission; additional display with humidity module: %RH, 
°Ctd

 



Optical and audible alarm when limit values are exceeded

 



TC probes compatible for determining emissivity

 



Can store 90 measurement protocols

 



Inc. PC software for archiving and documenting data and aluminium case for instrument and accessories
