Handheld Infrared Thermometers Product Description
The
TLC 720, Handheld Infrared Thermometers function as
non-contact infrared and contact thermometers. The user
can always toggle between the digital ir thermometer's
two operating modes. Additionally the portable infrared
thermometer has a laser pointer that helps the user aim
the temperature sensor at the target when they are
making measurements.
Non-contact temperature measurements
The ideal distance in most applications for the
non-contact digital infrared thermometers is from 4 to
12 inches, measuring a 0.8-2.5 inch diameter circle. As
the distance (D) from the object increases, the spot
size (S) of the area measured by the portable ir
thermometer becomes larger. Make sure that the target
is larger than the non-contact digital infrared
thermometer's spot size. The smaller the target, the
closer you should hold the handheld ir thermometer to
it. When accuracy is critical, make sure the target is
at least twice as large as the portable infrared
thermometer's spot size.
Emissivity
Inaccurate readings will result from using the handheld
digital infrared 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 portable infrared
thermometer to measure the temperature of the tape or
painted surface. When measuring a grill, for example,
aim the handheld digital ir thermometer at a portion of
the grill that has been blackened by the high
temperatures. The portable ir thermometers cannot
measure through transparent surfaces such as glass or
plastic. The handheld digital infrared thermometers
will measure the surface temperature of the transparent
surface instead. Steam, dust, smoke, etc., can prevent
accurate measurement by obstructing the non-contact
digital ir thermometer's optics. Hold the non-contact
infrared thermometer back and at an angle to ensure the
most accurate measurements.
Applications
The TLC 720 Handheld Infrared Thermometer is a handy
temperature measuring instrument for various measure and
control tasks in the trade, the industry, and the
laboratory. Applications for the non-contact digital ir
thermometer include fast, simple temperature
measurements of liquids, motors, pipes, food, storage
containers, received goods, supermarket areas, kitchens,
and refrigerated rooms. NOTE: When measuring liquid
products, be sure to stir the product vigorously while
using the portable infrared thermometer to measure the
surface of the liquid. Note: DO NOT submerge handheld
ir thermometers in water.
