TFI 550 NON-CONTACT THERMOMETERS

The TFI 550 non-contact thermometers are suited to a multitude of measurement and control tasks in industry, trade and crafts.  The non-contact thermometers are simple and efficient to use, all you have to do is aim the thermometer and press the measurement key.  The non-contact thermometer's optics record the emitted, reflected, and absorbed heat radiation which is bundled and focused on a detector.  The infrared non-contact thermometer's electronics change this information into a temperature value which appears on the display.  The non-contact thermometer's built in laser can be used to ensure that you are targeting the correct measurement point. 

Temperature values on the infrared non-contact thermometer can be switched between celsius and fahrenheit.  The temperature measurement can also be locked to display on the non-contact thermometer's LCD screen for 60 minutes or as long as lock mode button is depressed. 

Non-contact thermometer measurements
The ideal distance in most applications for the infrared non-contact thermometers is from 3.9 and 7.9 inches (100 and 200 mm); in this case, the size of the measurement spot equals approx. 0.1 to 0.3 inches (3 to 7 mm).  As the distance (D) from the object increases, the spot size (S) of the area measured by the non-contact thermometer becomes larger.  Make sure that the target is larger than the infrared non-contact thermometer's spot size.  The infrared non-contact thermometer's two laser points are the reference for the target spot size.  The smaller the target, the closer you should hold the infrared non-contact thermometer to it.  When accuracy is critical, make sure the target is at least twice as large as the infrared non-contact thermometer's spot size.
