Fluke FS100 Thermal Body Screener

For over 70 years Fluke has been a leader in test and measurement tools and over the past 20 years has become a leader in thermal imaging tools. When our customers started asking for a thermal imaging device to measure human body temperature, we were up for the challenge. Introducing the FS100 Thermal Body Screener*, a non-contact, thermal imaging system, engineered to detect elevated body temperature.

Manufactured in the United States

The Fluke FS100 thermal screening camera is engineered and produced in the United States, from our headquarters in Everett Washington. Fluke controls the entire process from production to calibration to maintain the high-quality tools that the world has come to expect from us. All Fluke tools, including the FS100, go through a rigorous testing and validation process, ensuring the accuracy, durability and overall quality of the tool.

Quick Results

With a measurement time of approximately one second, the FS100 system minimizes the productivity impact of a temperature screening process. The system is portable and assembles rather simply, enabling the ability for users to carefully select the optimal screening area. Note that to maximize accuracy of the system and adhere to FDA guidance, the FS100 conducts temperature screening on an individual basis (e.g., one person at a time).

Accuracy and Resolution

When it comes to measuring human body temperature, accuracy is one of the most important attributes, which is why Fluke focused on maximizing accuracy when engineering the Fluke FS100 Thermal Body Screener. Fluke’s +/- 0.25 C accuracy is defined as the difference between actual and expected readings using a secondary blackbody calibration source. When combined with other system uncertainties including stability, long-term drift, uniformity, and uncertainty in the accuracy of the temperature reference source, the combined accuracy of the Fluke FS100 system is +/- 0.5C. The FS100 utilizes a 640 x 480 infrared resolution camera, inferring 307,200 pixels of temperature measurements. For context, this means that when someone is standing at the specified distance from the camera each pixel is 〈1mm on each human face. The FS100 is for initial human temperature measurement only. Any elevated or suspected elevated body temperature measurement must be confirmed with a secondary evaluation method (e.g., non-contact infrared thermometer (NCIT) or clinical grade contact thermometer).

Facial Detection

The FS100 utilizes facial detection technology to ensure that the subject is properly positioned and has enough measurement points on the face to accurately measure the body temperature. The device can operate effectively within a range of 1.0 to 1.5M (4.9ft) from the subject to the camera and by doing so, the 640 x 480 resolution can be optimized, generating a reading in which each pixel that is measured is approximately 1 mm square of the human face. Consequently, providing measurement and assessment performance in accordance with IEC 80601-2-59. Facial detection technology enables the ability to ensure that temperature measurements of the facial region are actually captured, rather than unrelated items (e.g., a tumbler filled with hot liquid, etc.) that happen to be in the field of view of the thermal camera.

Social Distancing

In order to limit person-to-person contact, the CDC has recommended social distancing of 6 feet between all people. The Fluke FS100 enables social distancing by having each person move into the measurement area while maintaining 6 feet of distance between people. Additionally, the system can be set up so that the operator is also able to safely practice social distancing as well (e.g., with an operator of the FS100 6 feet from the subject, behind a barrier or in another room if desired).

ROI

Many companies today are employing outside resources, including medical professionals to assist with providing with screening for elevated temperature. The FS100 Thermal Body Screener can reduce the need for resources related to temperature screening services. The system offers a “plug and play” set up and can be operated with minimal training, allowing for an efficient and reliable temperature reading. Health officials should determine the significance of any fever or elevated temperature that is output from the FS100.

Accuracy is what matters

When engineering the FS100 Thermal Body Screener, Fluke made sure to consider several different factors to achieve our system level accuracy of +/ 0.5C. Please see below for a list of the relevant factors:

• Resolution
  • The FS100 uses the Ti480 PRO camera as its thermal imaging base. At a resolution of 640 x 480, we are capturing the most pixels on the human face as possible with highest resolution camera that Fluke produces.
• External Temperature Reference Source (ETRS)
  • The Fluke 4180ETRS is an external temperature reference source, allowing for traceability and accuracy of infrared body temperature measurements by continuously benchmarking against a known, stable temperature surface in the camera’s field of view. This allows for the system to continually reference a known temperature and to adjust accordingly for accuracy.
• Ambient temperature
  • Included in the system is the Amprobe TR300. This tool is a temperature monitor that is plugged directly into the system so that it can measure and communicate the ambient temperature of the screening area to the FS100 system.
• Relative humidity
  • The Amprobe TR300 also measures and communicates the relative humidity of the screening area to the FS100 system which further contributes to achieving accuracy by allowing the operator to confirm the humidity in the screening area is at an acceptable level.
• Facial detection
  • Utilizing facial detection, the FS100 measures the hottest point on the human face.

2-in-1 tool – Body temperature measurement and preventive maintenance

The Ti480 PRO included in the FS100 Thermal Body Screener is a versatile tool. Not only is the device suitable for screening human body temperature, but given the Ti480 PRO thermal camera base, the device can also be repurposed for facility maintenance. For example, when removed from the system the Ti480 Pro can be used for thermal scans of equipment, HVAC systems, or other practical uses within your facility. When needed for temperature screening it can easily be integrated back into the FS100 system.

Data Privacy

As a world class and trusted provider of Test & Measurement tools and software, Fluke naturally operates in environments with sensitive data that must be protected. To that end, Fluke strongly recognizes the significance of data privacy and has equipped the FS100 with data capture features applicable to a range of customer preferences. By default, unidentifiable data (i.e., date, time and temperature) is recorded when a subject with an elevated body temperature is identified. If preferred, settings can be adjusted in the software to capture thermal or visible light images at the moment when elevated temperature is identified.

The FS100 measurement should not be solely or primarily relied upon to diagnose or exclude a diagnosis of COVID-19, or any other disease. 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 skin tele thermographic temperature measurement. The technology should be used to measure only one subject’s temperature at a time; Visible thermal patterns are only intended for locating the points from which to extract the thermal measurement.
