Safety Precautions

Before using the thermometer, please read the following precautions carefully:


This product is not a substitute for continuous monitoring of body temperature

The temperature sensor is a sensitive part of the infrared thermometer and must be protected carefully.

Do not discard the used batteries at will and send them to the designated environmental protection place for disposal, so as not to pollute the environment. At the end of the service life of the device, there may be situations where normal measurement is not possible. Random disposal of discarded medical electronic products may cause environmental pollution. The inspection shall be disposed of according to relevant laws and regulations.

When the product is not used for more than 2 months, the battery should be removed and stored.
Do not immerse the product in water or expose it to the sun. which will cause damage or accelerate aging.

Do not shake or bump the product violently, it may cause damage or inaccurate measurement.
The normal temperature range of the human body varies from person to person. It is recommended that individuals record daily measured values as reference values for fever.

Body temperature rises during exercise or emotional agitation, and measurement is not recommended at this time. Take a break for 20 minutes after exercise before taking measurements.
After each use, it should be cleaned and stored in a dust-free, dry and ventilated place.

● Avoid measuring in an environment outside the specified normal working environment, which will adversely affect the accuracy.

● Avoid storing and transporting in environment outside the specified storage and transport environment, which will adversely affect the accuracy.

●During use, if the thermometer is dropped or damaged due to carelessness, and the normal measurement reading cannot be provided, it is not recommended to continue to use, please contact the dealer or the manufacturer's after-sales service department for consultation and treatment. Don’t open or repair the device by yourself



This product cannot replace monitoring equipment for continuous monitoring of body temperature.

● It is dangerous to perform self-diagnosis and treatment through the measurement results, please refer to the diagnosis of a professional doctor.

● Do not modify this machine without the manufacturer's permission to avoid damage or safety hazard.

   Do not charge or throw ordinary dry batteries into a fire to prevent the risk of explosion.

    Non-professionals should not disassemble or repair the thermometer to avoid irreparable damage.

   When measuring, please do not use mobile phones or other electromagnetic interference equipment in the surroundings.

It is forbidden to use this equipment in a mixture of flammable anesthetic gas and air or with oxygen and nitrous oxide.

Keep the thermometer out of the reach of children

Product description

(1) Product structure and composition

This product is mainly composed of plastic case, LCD display, operation

buttons, infrared temperature sensor, and circuit components.

(2) Measurement principle

Measure the infrared energy emitted from the forehead. This energy is concentrated through the lens and converted into a temperature value by a thermopile and a measurement circuit.

(3) Scope of application

● Display the body temperature of the measured object by measuring the heat radiation of the human forehead.

(4) Contraindications


(5) In normal use, the accuracy of measurements obtained with IR thermometers and contact thermometers are the same, but sometimes it may be affected by operators’ technique, anatomical variations, subject cooperation, etc. so suggest using the infrared thermometer according to the user manual strictly

Precautions before use

1) --At least 30 minutes required of equipment to warm from the minimum storage temperature until it is ready for intended use,

2) --At least 30 minutes required for ME equipment to cool from the maximum storage temperature between uses until it is ready for intended use.

3) The body thermometer is suitable for indoor use, and the instrument itself and the test subject must not have a large air convection during the measurement (such as the wind from an electric fan, air conditioner, or heater);

4) This machine is sensitive to the ambient temperature, do not hold it with your hand for a long time;

5) Please make sure the sensor head is clean and unobstructed before use;

6) When measuring forehead temperature, please make sure that your forehead is not covered by hair, etc.

7) Please ensure that there is no intense mood, exercise, etc. before the measurement;

8) The test subject from one environment to the measurement environment, if the temperature is different, it is recommended to rest at least measure over 10 minutes.
