The OS-VIR50 video infrared 
thermometer is capable of making 
non-contact (infrared) and contact 
(thermocouple) temperature 
measurements. The built-in camera 
offers still image and video capturing 
functionality for documenting 
measurement locations. The meter 
includes a microSD card slot for 
offloading still images and video. 
The built-in laser pointer increases 
target accuracy while the backlit 
LCD and handy push-buttons 
combine for convenient, ergonomic 
operation. This meter is shipped fully 
tested and calibrated.
