Flir TG56 IR Thermometer Measures Non-Contact and Contact Temperature is an advanced new meter for taking non-contact temperature readings at a distance with a excellent 30:1 distance to spot ratio for safely taking temperature readings of hard-to-reach targets and for taking differential measurements using a contact thermocouple probe. The Flir TG56 is designed with an easy-to-navigate color display screen that displays the last two temperature simultaneously with the current reading for easy differential calculations. The TG56 also has selectable preset emissivity as well as manual adjustment, visual high and low alarms and is ruggedly designed to withstand a 3 meter drop.
