Introduction
This series of hand-held Infrared Thermometer is our company newly developed high-
performance and high-quality instrument which uses ARM single-chip computer to
collect and process data. The instrument has the functions of emissivity adjustment,
maximum value, minimum value, overage value, temperature difference value, high and
low temperature alarm setting. It has the advantages of high measurement accuracy, fast
response speed, simple operation and reliable use. It can be widely used in petroleum,
chemical, railway, electric power, textile, plastic, metal processing, energy-saving and
other industries to quickly and non-contact measure the surface temperature of objects.
All objects which temperature is higher than absolute zero are constantly radiating
infrared energy. There is a certain functional relationship between the infrared energy
radiated by the object and the surface temperature of the object. By measuring the infrared
radiation of the object itself, the surface temperature of the object can be accurately
determined, which is called infrared temperature measurement. The infrared thermometer

is generally composed of infrared optical system, infrared detector, electronic circuit and
other parts.
The infrared optical system gathers the infrared energy radiated by the object within the
field of view, imaging on an infrared detector, the infrared detector converts the energy
into electrical signal, which is amplified by the electronic circuit and the single chip
microcomputer calculates and processes various data and displays the surface temperature
value of the measured target.

Emissivity table
Appendix 1 Method for determining emissivity
−The emissivity of common materials is listed in Appendix 2 for users' reference;
−The emissivity of materials was measured by direct measurement The real temperature
of the material is measured by contact thermometer, and then measured by Infrared
Thermometer, adjust the emissivity value of the instrument until the measured
temperature is equal to the real value, the emissivity at this time is the emissivity of the
material.
−The Material which is impossible to measure directly, with low emissivity should be
pasted on the surface of the material with black tape or sprayed with black paint (the
emissivity of black tape and black paint is EMS = 1.00). After the temperature of the

material reaches balance, use infrared thermometer (the preset emissivity is 1.00, 0.1-1.00,
adjustable) measure the temperature of the cover on the material and adjust the emissivity
value of the instrument until the measured temperature is equal to the real temperature,
and the emissivity is the emissivity of the material.
For the determination of emissivity value, please refer to Appendix I and 2. Appendix 2

Precautions
−The relationship between temperature measurement and target size and distance The
relationship between the distance between the infrared thermometer and the target size is
expressed by the object distance ratio. The definition of the object distance ratio is the
ratio of the distance D from the measured target to the infrared thermometer and the
effective area s of the measured target (D: 5), which is the optical index of the infrared
thermometer. Through the object distance ratio, the measurement distance can be
determined according to the size of the measured target. The object distance ratio is 50:1.
In order to reduce the error in actual measurement, the target size should be full of the
field of view measured by the instrument, and it is better to make the target size more than
twice of the field of view spot.
−The influence of emissivity on temperature measurement Emissivity represents the
thermal radiation ability of the object surface. Due to the different material and surface
state of the object, its ability to radiate infrared energy is different. In order to compensate
the measurement error caused by different emissivity, the instrument should be adjusted
according to the material of the object. The emissivity value of the instrument should be
adjusted according to the material of the object (In the appendix, the emissivity values of
some materials and the determination methods of emissivity are attached for reference).
Laser radiation is harmful to human eyes. When using, do not point the laser beam at
people's eyes. The technical specifications of the laser used in the infrared thermometer
are as follows:
Outlet power: < 1MW
Wavelength: 650nm
Laser grade: Grade II
Operating distance: about 30m
-10-
−The instrument should avoid contact with overheated objects, objects with strong
magnetic and strong current, corrosive objects such as lipids, ketones, ethylene and
dichloride.
Instrument maintenance
−Lens cleaning:

After the infrared thermometer is used for a period of time, dust will be accumulated on
the lens. Clean ball can be used to blow off dust on the surface or clean cotton swab is
used to clean the lens surface with a little water.
−Shell cleaning:
A soft cloth stained with neutral cleaning solution can be used to wipe the thermometer
shell.
−Replace the battery:
When the power indicator on the LCD has no level, please replace the battery in time. In
order to protect the environment, please dispose of the replaced batteries properly.
−When the instrument is not used for a long time, please take out the battery and store it.
−If the instrument foils, it should be repaired after being confirmed by the manufacturer
or dealer. The user should provide the text description and packing list of the failure
phenomenon. The packaging of the instrument should be well buffered and protected.
