Handheld / Portable

TEquipment carries a variety of thermal imagers for measuring temperature in humans. Although these cameras are handheld and portable, they also accept standard tripod mounts. This provides the versatility of on-the-go screening throughout a facility, or setting up a temporary station at a building’s entrance.

To select a thermal imager for human screening, here are a few factors to consider:

• Is this device designed for measuring temperature in humans? 
  • Most thermal imagers are designed for industrial applications and a completely different temperature range
• What thermal resolution do you need?
• Will this work with the physical size of your screening area?
  • These cameras can accurately measure temperature up to a certain distance away. Will this distance work for your facility, or is it too short / too long?

Thermal resolution refers to how many individual temperature points the camera will measure at a given time. This number is obtained by multiplying the height and width of the sensor size. For example, the FLIR E54-EST has a sensor size of 320 x 240. Therefore, it will simultaneously measure 76,800 individual temperature points. These are color coded according to temperature, which then form a thermal image.

Why does thermal resolution matter? Many cameras use the tear duct as a measurement point. A high resolution is necessary to measure something that small from several feet away.

It is also important to select a product from a known and established manufacturer – there are now products on the market from companies that didn’t exist a year ago. They are low dollar, low resolution devices sold with impossible claims of accuracy and measuring distance. You will not find products like this on TEquipment.

FLIR

FLIR has been a leader in thermal imaging for decades and offers a full line of cameras specifically designed for human temperature measurement. Their EST series is available in several styles, with a variety of lenses, form factors and thermal resolutions. These devices are also FDA registered.

These cameras feature a built in screen and can also output content to an external monitor. The FLIR software provides easy to follow, color coded results so the testing process is both fast and easy. In addition, these cameras can be either tripod mounted or held by hand.

The thermal resolutions for these are listed below. The E54-EST is the most popular product in this series and is suitable for many different scenarios.

• E54-EST – 320 x 240
• E86-EST 24 – 464 X 348
• T540-EST 24 – 464 X 348
• T560-EST 24 – 640 x 480

Jetion JT-66K

The JT-66K offers an outstanding value. This thermal imager features a 160 x 120 thermal resolution and can be connected to a computer to view test results in real time. Screening personnel can safely view results from a distance and are alerted when a temperature alarm has been triggered. The camera and computer connect with a standard USB-C cable.

This camera can be handheld, but also ships with a tripod for more stable usage.

The JT-66K has an accuracy of 0.9°F over the temperature range of 86-113°F and measures from a distance of 3.3 feet (1 meter).

PC software is included.

Hikvision DS-2TP31B-3AUF

The DS-2TP31B-3AUF is a great product for preliminary screening.

It features a 160 x 120 thermal resolution and has an accuracy of ±0.9°F accuracy over range of 86-113°F. It has a measurement distance of 3.3 feet (1 meter), and contains a built-in, rechargeable Li-Ion battery for up to 8 hours of continuous operation.

Results are viewed on its full color, built in 2.4” LCD display. This product can also be either handheld or tripod mounted.

Please note – this cannot be hooked up to a computer to view results remotely in real time.
