Fluke FS100


Thermal Imaging Body Screener Kit



The Fluke FS100 Thermal Imaging Body Screener Kit is a non-contact, thermal imaging system, engineered to detect elevated body temperature.

Manufactured in the United States

The Fluke FS100 is engineered and produced right here 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.

The System

The FS100 Thermal Body Screener Kit is a hardware and software solution for human temperature screening. Defined as a Telethermographic System, the product determines human surface skin temperature based on a thermal image that is calibrated by an External Temperature Reference Source (ETRS).

Elevated body temperatures (EST) based on FS100 output need to be confirmed by a secondary method, such as a non-contact infrared thermometer or clinical grade contact thermometer.

It is important to use a calibrated temperature source to ensure accurate measurements. The Infrared Thermal Imaging Camera (IR Camera) and ETRS provide data to the Software. The Software interprets this data, and within 1 second or less, the operator sees if a test subject's temperature exceeds pre-determined limits.

Product usage includes temperature assessment for high-throughput areas such as building entrances, airports, factories, and more.

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 the following for a list of the relevant factors:


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.

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 a facility. When needed for temperature screening it can easily be integrated back into the FS100 system.

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.

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 [not inferring, but rather providing] 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 measuring a 1mm area 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 Distance

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).

Return on Investment

Many companies today are employing outside resources, including medical professionals to assist with providing with screening for elevated temperature (EST). 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.

Data Privacy

As a world class and trusted provider of Test and 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 (EST) 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.

Example Set Up

1. Install camera shutter onto the camera.

2. Physically mount the camera on the tripod and move the tripod to desired location, then connect power and communication cables to the camera.

3. Physically mount the ETRS on the provided shelf and tripod and move it to desired location, then connect power and communication cables to the ETRS.

4. Connect the power and USB cable to the TR300 to the PC.

5. Physically position screens if necessary to prevent reflections onto the camera and ETRS.

6. Connect communication cables to PC.

7. Turn on camera, ETRS, and PC.

8. Launch the PC software to take temperature measurements.

FS100 PC Software

The FS100 PC software allows the operator to view the test subject's temperature. With a green "PASS" or a red "WARNING", as indicators of a temperature that is below or above the threshold, the operator is able to quickly let the test subject know of the next step.

The FS100 utilizes the latest in 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. By ensuring the subject is 1 meter away from the sensor each pixel that is measured is <1 mm square of the human face.
