The Infrared Thermometer measures the body temperature by collecting infrared thermal radiation from the forehead of the human body. Its operation is simple and hygienic, and the measurement is fast and accurate. The user only needs to point the probe head at the forehead and press the measurement button, and the body temperature can be quickly and accurately measured in 1 second, which can be used by the family and medical departments to measure the body temperature. This product is a type 2 medical device, which belongs to the internal power supply equipment, type B application part, and the protection class is ordinary equipment (IP20). Do not use it in the presence of flammable anesthetic gas and air, nitrous oxide gas, for continuous operation of the equipment. The EU classification is Ilb.
Scope of Application:
Used by families and medical departments to measure Body/Surface temperature.
Product Features:
- A top-quality infrared sensor ensures very few variations.
- Great Environment adaptability. Works in most environments.
- A new control probe structure ensures more accurate measurement.
- Conveniently switch between human and object modes with just one button press.
- High-Temperature alarm with red backlight color.

Setting Operation
The Thermometer comes with three settings: Surface selection, prompt tone on/off, and selection of measuring unit(°C and °F)
The comparison table of setting menu is as follows:
| The Menu | Function | Set | + | – | The Initial Value |
| Fl | Surface Selection | Press Setting for F2 | Prompt | No Prompt | Prompt |
| F3 | Measuring Unit | Press Again to Finish | oC | °F | oC |
- Setting of Forehead Temperature/Object Mode Conversion At start-up, press and hold “SET” till the screen displays Fl. Press “+” or “-” button to toggle the surface between human and object. Choose appropriately.
- Prompt Tone Switch Setting At start-up, press and hold “SET” till the screen displays Fl on the screen. Press “SET” once to use F2 setting. Press the “+” or “-” button to switch the prompt tone on and off.
- Celsius/ Fahrenheit Setting At start-up, press and hold “SET” till the screen displays Fl on the screen, & press “SET” twice to use F3. Press the “+” or “-” button to toggle between Celsius/Fahrenheit.
SAFETY INSTRUCTIONS
3.5.1 Measurement of Human Body Temperature
- After loading the battery, press the trigger button for 2 seconds.
Make sure the measuring mode at the top of the screen is body mode.- Aim the thermometer probe at the bare body- head or arms, whilst maintaining a distance of 3-5cm. Then press the trigger to record the temperature. The target’s temperature will display on the screen 1 second after pressing the trigger.
- The thermometer will automatically shut down after 10 seconds if left idle.
- 320C – 37.3°=> Green Light; 37.40C- 37.90C => Yellow Light: Temperature >_38°C above, Red Light.
Temperature <32 GC => Red Light and shows “LO”. Temperature > 42.9 0C => Red Light and shows “HI”.
Warm Prompt
- Keep the inner cavity of the sensor and probe clean before and after use.
- Place the thermometer in a stable temperature environment. When the ambient temperature varies greatly (e.g. from indoor to outdoor), Please leave it for about ten minutes and then measure it.
- Do not measure the temperature of an extremely high or low-temperature object. Start taking your temperature immediately. Leave it for ten minutes.
- When there is a big difference in the temperature of the surface relative to the environment let the thermometer adjust to the environment for 5 minutes and attempt again.
- For accurate readings, wait 30 minutes after exercising, showering or eating before measuring temperature
3.5.2 Object Temperature Measurement
- Toggle the measurement mode to objects
using the function key. - Point the thermometer probe at the measuring object about 3-5cm away. Then press the trigger to record the temperature. The target’s temperature will display on the screen 1 second after pressing the trigger.
Warm prompt
- The theoretical range of object temperature measurement mode is 00C-1000C.
- This thermometer measures the surface temperature of an object and does not represent the core temperature of the object.
- The emissivity of different materials may be different (please refer to the material emissivity). The measured temperature will slightly vary from the actual temperature.
Temperature <32 °C => Red Light and shows “LO”. Temperature >42.9 DC => Red Light and shows “HI”.
Product maintenance method, storage and transportation conditions and methods
Product Maintenance Method :
Since the product is a reusable device, please pay attention to the cleaning process after use. Please keep the inner cavity of the sensor and probe clean, otherwise, the measurement accuracy will be affected.
