Getting Started: Beurer® Non-Contact Thermometer (FT 95)

The Beurer® Non-Contact Thermometer (FT 90) is a non-contact body temperature sensor as a standalone device and in OpenSignals use.

Learn how to use this device with your next biosignals recordings and more in this article.


  • Non-Contact measurement technology via infrared light
  • Compatible with biosignalsplux and BITalino products in OpenSignals Desktop
  • Standalone: record data without PLUX devices using the device’s built-in display (up to 60 readings)
  • Bluetooth Low Energy (BLE)-enabled (support for OpenSignals & PLUX APIs coming soon)


  • Non-contact measurement via infrared
  • Flexible measuring tip
  • Output units: °C and °F
  • Body temperature accuracy (at forehead): ±0.2°C: 34°C-42.2°C (±0.4°F: 93.2°F-108°F)
  • Visual temperature feedback (green: ok; orange: slightly elevated body temperature; red: fever)
  • Acoustic feedback when the measurement is concluded
  • Battery-powered: 2×1.5V AAA batteries (included)
  • Product Dimensions: 16.7 x 4.2 x 2.8 cm
  • Product Weight: 74g (excl. batteries)

Device Interface

The device consists of the following interfaces, which will be referenced during the first setup and use of the device.

First Use

The Beurer® Non-Contact Thermometer (FT 95) comes with everything needed to record temperature data. 

During the first use, you’ll need to insert the included batteries into the device by removing the battery compartment lid on the backside of the device, inserting the batteries, and closing the lid again.

Start the device by pressing the power button (if the device has not already started itself after placing the new batteries) and the device will initiate a process to set up the following functions individually:

Use the MODE/MEM button to set your preferred input and the LIGHT/SET mode as the confirmation button.

Measuring Temperature Data

Ensuring the Right Conditions

This device uses infrared light to measure skin-surface temperature at the forehead from which the body temperature is taken. Ensure that your measurements are taken under the right conditions for best data quality and reliability:

  • Avoid taking measurements after switching ambient temperatures. For instance, if your subject comes from a colder ambient temperature, taking any readings immediately after this change might invalidate your measurements. Allow the subject sufficient time to accommodate to the new ambient temperature.
  • Physical activity, increased perspiration on the forehead, taking vasoconstrictive medication and skin irritations can distort the measurement.
  • The forehead, or the temples, must be free from perspiration and cosmetics.
  • We recommend that you take three measurements on the forehead. If the three meas-urements are different, use the highest value.
  • If the forehead area is covered in hair, sweat or dirt, clean the area and then wait for10 minutes to improve the precision of the measurement.
  • It is important that you keep the thermometer still during measurement. Moving the ther-mometer during measurement may cause imprecise measurements.


  1. Start the device by pressing the power button. The device will conduct a brief- self test and two short beeps will indicate that it is ready for forehead temperature measurement.
  2. Hold the thermometer 2 to 3 cm in fron tof the forehead
  3. Press the SCAN button to initiate the measurement
  4. The device will display the measured temperature shortly after including green, yellow, and red indicators categorizing the temperature as “no fever (<37.5°C )”, “increased temperature (<37.9°C )”, and “above normal temperature (>37.9°C)”.

Logging the results in OpenSignals Desktop

Results recorded by this device can be manually logged into your OpenSignals recordings during real-time acquisition and in post-processing using the Manual Measurements tool.

Documentation & Other Information

Beurer provides their own line of health apps for their products. These apps may be available free of charge in the iOS App Store and Google Play store but are not compatible with PLUX software. PLUX does not provide any support for native Beurer apps.
