Apply Range:

It can be widely used in the property, home, electricity, heating, ventilation, transportation and other fields, by scanning all on-site electronic devices - breakers, switches, transformers, fuses, bus and power strips to find the hot spots.
Suitable for field testing HVAC supply / return air temperature: Detection of indoor air temperature, to ensure that air conditioning work. Also used to measure the movement of charged and difficult to access the object's temperature, to avoid foods, chemicals, medicines measurement cross-contamination and physical damage.

4 Field

1) to ensure that the measured object is larger than the instrument infrared circular light spot diameter.

2) The smaller the target, the thermometer should be closer to the target.

3) Make sure that the measured object area not less than twice the measuring point.

4) to ensure that the measured object is larger than the instrument infrared circular light spot diameter.

5 Hot positioning: To find a hot spot, aim the thermometer outside the area measured, and then slowly moved up and down the thermometer to scan the entire area until the test points to determine hot spots.

6 Tips

1) can not be transmitted through the transparent surface of the instrument (such as glass) measurements.

2) Steam, dust, smoke, etc., from the surface barrier infrared instrument affect the measurement accuracy.

7 for measuring the distance and the object target ratio: Optical measurement than the target and the object distance D: S = 12:1, for example: the instrument field of view is 12:1, the instrument from the measured object is 12 inches, then the measured object not less than 1 inch in diameter. The following figure shows the other distance measuring range:
