Introduction 

 

 

Congratulations on your purchase of the Triplett Model IRT227 Mini IR 
Thermometer. 
 
The IRT227 IR thermometer measures and displays non-contact (infrared) 
temperature readings and ambient air temperature. In addition, the Type K 
thermocouple provides contact temperature measurements. 
The  built-in  laser  pointer  increases  target  accuracy  while  the  backlit  LCD 
and handy push-buttons combine for convenient, ergonomic operation. The 
adjustable  emissivity  feature  allows  the  IR  thermometer  to  measure  the 
temperature of virtually any surface.
