Model Dt8380 Type Handheld Applicable object Industrial object thermometer
Measuring range -50~380°C Measurement accuracy 2% or 2°C Resolution 0.1
Size 160x88 x 40 mm

Working principles:
Any object with a temperature greater than absolute zero radiates infrared energy.This energy travels around at the speed of light.The lens of the infrared thermometer collects and assembles infrared energy on the sensor, which produces a low voltage output that is proportional to the temperature of the target object.The voltage output is shown as a temperature value after processing.
Description of operations:
-pull the trigger to turn on the power supply, display reading and battery icon.Loosen the trigger and keep reading about 15 seconds.
-locating the measurement point: to locate the measurement point, press the trigger, grab the temperature outside the area to be measured, and scan the whole area up and down until the measurement point is found.The screen will read the temperature continuously.
Note: hold the trigger for no less than 1 second.
● Under f/°C key, can switch temperature from fahrenheit to centigrade.
● According to▲Key, can open or close laser positioning
● Make sure the target object is larger than the measuring point, which is calculated by (the field map or the instrument itself).When accuracy is important, make sure that the target is not less than twice the measurement point.

Field of view: the farther the target is, the larger the measuring point of the instrument.The relationship between distance and measurement point size is usually expressed by the ratio of distance to measurement point size, as d: s.
Emission rate: most organic materials and surfaces coated with paint or oxidation have a emission rate of 0.95, pre-set emission rate in thermometers and 0.95 in thermometers.Measuring the polished or polished surface of the metal will result in an incorrect reading.The solution is to cover the measuring surface with black tape or black paint, and to measure the surface temperature of tape or paint when the tape reaches the same temperature as that of the covering material.
Note:
-not recommended for the measurement of bright or polished metal surfaces (stainless steel, aluminum, etc.)
-the thermometer cannot be measured through a glass-like transparent surface, which he will measure.
-steam, dust, smoke, etc. can affect the accuracy of measurements.
Maintenance:
Lens cleaning: blow loose particles off with clean compressed air, gently brush with soft hair to remove debris, and carefully scrub with wet cotton balls.
Note: don't wash plastic lens with solv
