Infrared Thermometer

TM0819

Many thanks for choosing our product. TM0819 is an infrared thermometer that can provide an accurate result of temperature
measurement with the help of laser beam.

The following are the major features of TM0819:

• High accuracy: Equipped with high-quality sensor to measure the amount of infrared radiation from objects.

• Time-saving : Only a press on the trigger is needed for measurement.

• User-friendly : Laser beam allows you to aim at objects more easily.

• Adjustable: Maximum and minimum temperatures can be displayed.

TM0819 is the ideal selection for electrician, maintenance personnel, technicians and even the emergency personnel.

2. Safety

Be cautious when laser is working

Do not point directly into eyes or anything that can reflect the laser
beam into eyes.

Do not point the laser directly at the explosive gas or flammable goods.

1. Point the instrument to the surface of the object and press the trigger.

2. It can display temperature, max temperature, min temperature, dierence value, average value, max

warning point, min warning point, external probe (not included in this product) measurement unit.

3. The measuring result will stay on the screen for 7 sec after the trigger is released and it will power o if

there is no other operation. Notice: Press the "MODE" button for 2 sec when the instrument is on to swift
between °F and °C.

5.1 Temperature Measuring

Dual laser distance is within 120cm, the temperature measured is 10cm in diameter at this distance.

5.2 Dual laser spot

1. Press and release the trigger

2. When "hold" is displayed, press the laser

backlit button to power on and o the
laser and to switch the backlit.

The max temperature is displayed in "MAX" after the temperature measurement is nished.

5.4 Max Temperature Display

1. Press and release trigger

2. Press the backlit button when the screen shows "HOLD" to switch backlit.

3. When the backlit is on, it will light up the screen.

4. Backlit will be remained stored stage until it change to another model.

Press up and down button to adjust emissivity when it shows "HOLD". The emissivity of this instrumentis
between 0.1-1.0.

Remark: backlit will consume the power of battery. Turn it o when you need not.

5.5 Backlight

1. It can enter max value, min value, average value, max alarm point, min alarm point, external probe

(not used).

2. Press and release the trigger when it shows "HOLD". Press the "MODE" to enter the next program.

Max Data Only shows the max data when measuring.

Min Data Only shows the min data when measuring.

Difference Shows the dierence between the rst and subsequent data.

Average data Shows the average between the rst and subsequent data.

HAL To set the max alarm temperature, press the up and down menu.

LAL To set the min alarm temperature, press the up and down menu.

This product can alarm when the temperature is too high or too low. It can make a sound to remind the users.

You can set the alarm temperature through the "MODE" menu. Setting will be saved even when device is turned
o.

°F and °C can be set by the temperature unit switch menu, press the MODE menu for 2 sec.

5.7 Temperature Unit

If the temperature is beyond the read range, it will shows "----" on the screen.

6. Attention

The object being measured must be larger than the vision eld of the instrument.

Keep the object surface clean and free from frost, oil and dirt etc. when measuring.

If the object's surface is reective, cover with adhesive tape or black paint before measuring.
If the object is transparent such as glass it may not have an accurate result.

Steam, dust, smog etc. will inuence the measuring result.

This instrument can adjust the environment temperature deviation. But if the deviation is huge it may take
about 30 minutes to adjust.

To nd the hot spot please point the object from top to bottom and from left to right until found.

When it shows low power signals "LOG", please replace battery (9V ). The battery is located under the trigger.

Properly dispose of the battery.

7. Distance Coecient Ratio

P. 8

Infrared Thermometer

8. Emissivity and Infrared Temperature
Measurement Principle

The distance coecient ratio of this product is 12.1. For example, if the object to be measured is 72cm far from
the instrument, then the diameter of the object must be larger than 6cm. It can measure proper distance but can
be inuenced by other light source.

Infrared thermometer is an instrument that measures the surface temperature. It is through infrared emission,
reection and then converted into energy. Thermometer converts the electrical signals into temperature reading
displayed on the LCD.

The infrared energy released is in direct proportion with its temperature and emissive power. This is called
emissivity. It is related to the material and gloss of the object. The emissivity value ranges from 0.1 to 1.0.
The emissivity of most organic material; paint and the surface be oxidized is 0.95. If there is a problem please set
the emissivity to be 0.95.
