I. roduct Introduction
It is a professional hand-held non-contact infrared thermometer, which is characteristic of easy operation, precise design, high
accuracy and wide measurement range. It possesses various kinds of functions such as laser collimation, LCD display with
backlight ，over-temperature alarm, adjustable emissivity and automatic shutdown. When the device is in use, the objects
temperature could be detected rapidly and accurately by simply aiming the detection window at the objects.
II. Basic Operation rinciple
Any object with the temperature over 0°C will emit a certain proportion of infrared radiation energy on the basis of its own
temperature. The radiation energy and its wavelength distribution have very close relation to its surface temperature. On the
basis of this principle, the objects temperature could be accurately detected by measuring infrared radiation energy of the
objects.
III. roduct Features
● Exclusive use of HEIMANN infrared temperature probe with high accuracy and stable performance.
● Sound alarm function when temperature is slightly high (Threshold value is adjustable)
● Backlight LCD digital display
● Two temperature modes to select: Fahrenheit and Celsius
● Max value, min value, relative value, average value and lock storage function
● Emissivity 0.1-1.00 adjustable
● Inbuilt laser aiming device
● Automatic shutdown (power conservation)
● Small volume, proper structure and easy to operate.

V. Operation Method
●Safety Notes
1. Please use with care when laser beam is turned on.
2. Don't aim laser beam at the eyes of people and animals.
3. Don't aim laser beam at the surface of objects which reflects to the eyes of people.
4. Don't aim laser beam at any explosive gas.
●Measuring steps and method
1. To measure a more accurate temperature value, this thermometer should be used
after 10 minutes when the batteries are installed. When the device is used in a
new environment, it should also be used after 10 minutes.
2. Aim the measuring probe at the measured object and press the measuring key on
the handle. The device automatically turns on with a beep sound. Meanwhile,
it will display the measuring result.
Note:
Please select the emissivity of the measured object and adjust the measuring distance according to the size of the measured
objects.

Battery Power Indication
HR When “HR” shows on the display,it means the environment temperature is too high.
Ⅶ. oints for Attention
1. The sensor lens is the most delicate part of the thermometer, so special care should be given to it.
2. They way to clean the sensor lens: gently wipe the lens by using a soft cloth or cotton swab with water or medical alcohol.
3. Don't put batteries in fire. Please place the used batteries at appointed recycling places. The use of unqualified batteries is
likely to cause fire or explosion.
4. When the device is not used for a long time, please take out the batteries.
5. Don't put the device in water or expose it to excessive heat.

6. Don't crush or throw the device in case it gets damaged.
7. The measuring discrepancy happens if the device is not within effective distance or not aimed at the center position of the
measured object. It is recommended to measure once again or more.
Ⅷ. Quality Commitment & After Sale Service
The warranty period is a year from the date of the original purchase.
Note:
1. The warranty is not extended to products that are physically damaged or that are not under normal operating conditions as a
result of misuse on the user’s part.
2. Please keep your warranty card and purchase receipt for warranty use.
