Product Description
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.
Non-contact thermometer emissivity
Inaccurate readings will result from using the infrared non-contact thermometers to measure shiny or polished metal surfaces like stainless steel or aluminum.  To compensate, cover the surface to be measured with masking tape or flat black paint.  Allow time for the tape to reach the same temperature as the material underneath it.  Use the non-contact thermometer to measure the temperature of the tape or painted surface.  When measuring a grill, for example, aim the infrared non-contact thermometer at a portion of the grill that has been blackened by the high temperatures.  The non-contact thermometers cannot measure through transparent surfaces such as glass or plastic.  The infrared non-contact thermometers will measure the surface temperature of the transparent surface instead.  Steam, dust, smoke, etc., can prevent accurate measurement by obstructing the non-contact thermometer's optics.  Hold the infrared non-contact thermometer back and at an angle to ensure the most accurate measurements.
