Non-contact thermometer

Contact free 25-70cm temperature measurements

Experience the future of temperature measurements with the CIR-100 non-contact infrared thermometer. Designed to prioritize safety and efficiency, this cutting-edge device allows you to measure temperatures from a comfortable distance of 25 – 70 cm, without any physical contact.

Say goodbye to traditional thermometers that require close proximity – the CIR-100 utilizes advanced infrared and laser-based sensing technology to provide accurate readings of the forehead temperature. With a range spanning from 34°C to 43°C (93.2°F to 109.4°F), it delivers precise results quickly and conveniently. Revolutionise your temperature monitoring process with the innovative CIR-100 today.

Application Focus Areas


Accurate over a distance from 25-70cm 

This non-contact thermometer combines sensor information from the various sensors and blends it with smart algorithms that do an accurate detection of a person’s face. This results in an accurate temperature measurement comparable to oral body temperature over a distance between the forehead and the  thermometer ranging from 25-70cm.

Benefits of non-contact thermometers

CIR100 available as health kiosk

Fast measurement results

The complete temperature measurement is done in only a few seconds. Stand in front of the thermometer. Start the measurement and the results are available in a few seconds.

Fully unobtrusive

The non-contact thermometer has a wide tolerance on how the user is positioned in front of the device.  This combined with the wide distance range results in possibilities to take accurate temperature measurements with minimal disturbance of the users. No more thermometers directly in your face. This enables new autonomous temperature sensing possibilities without involvement of additional personnel.

Standalone device or complete temperature screening solutions

2M delivers the CIR100 as standalone device for integration into third party kiosks. 2M also provides compete temperature screening solutions based on your requirements. Solutions that provide instant temperature readings or store them.

Oral body temperature

The CIR-100 measures the temperature of the forehead and provides the forehead temperature and the translated oral temperature in the range of 34°C – 43°C (93.2°F – 109.4°F).


The CIR-100 laboratory accuracy is ±0.5˚C over the full measurement range from 25-70 cm when used indoors.

Fast measurement

Temperature measurements are completed within 5 seconds. The CIR-100 is calibrated by the manufacturer and does not need recalibration over its lifetime.

Smart algorithms

The camera uses smart algorithms to deliver an accurate temperature reading under specified use conditions. All processing is done within in the CIR-100.


The CIR-100 can be integrated into larger systems. Customizations and extra features are possible on request.


The CIR-100 is powered via the USB interface on the back of the unit. This USB interface is also used for serial communication with the device. Extensive API documentation is available to make integration easy.

Intended use of the CIR100 non-contact thermometer

CIR-100 is a non-contact Infrared Temperature Sensor which measures the temperature of a person at a distance of 25 – 70 cm, without coming in contact with them. It measures the temperature of the forehead and provides the forehead temperature and the translated oral temperature in the range of 34°C – 43°C (93.2°F – 109.4°F).

The device should be used to measure only one subject’s temperature at a time. The device is intended to identify persons suspected of having a fever to prevent them from entering a specific location. CIR-100 provides a temperature measurement of a person. Public health officials, through their experience with the device in the particular environment of use, should determine the significance of any fever or elevated temperature based on the measurement.

When the device indicates an elevated body temperature, a secondary screening with a clinical thermometer should be performed. The measurement should not be solely or primarily relied upon to diagnose or exclude a diagnosis of COVID-19, or any other disease.

The CIR-100 non-contact thermometer has been authorized for use in the USA under Enforcement Policy for Telethermographic Systems During the Coronavirus Disease 2019 (COVID-19) Public Health Emergency.

How the CIR-100 works

The CIR-100 contactless infrared temperature sensor scans the face and uses smart algorithms to compute the oral body temperature. The accuracy is achieved by combining infrared sensing techniques with laser based photonics and 2M’s smart algorithms.

Taking a measurement

The user stands in front of the CIR-100 at a distance of 25-70cm. If the user is not standing within range the device indicates the user how to correct its position. Within seconds after the measurement has been started it communicates the measured temperature values over the USB interface to a connected device where it is displayed. This can be a computer, Android device (integration with other operating systems on request) or remote display (not included). 


The Infrared Temperature Sensor is connected via a USB interface to a computer, which powers the device and handles the communication with the device. Measurements can be started from the computer after which the temperature sensor send back the temperature value according to the defined API.

Extensive API documentation and sample code is available for easy integration.
