FLIR E40 Features

FLIR MSX Image Blending

The FLIR E40 incorporates FLIR's unique and powerful MSX imaging blending technology. MSX stands for Multi-Spectral Dynamic Imaging. This technology extracts details and highlights from images taken by the E40's built-in digital camera and combines them with identical infrared images in real time to create a blended thermal image. In blended thermal images, features such as numbers, labels and textures are clearly visible. This makes identifying thermal images and areas under test much easier.

Combined - MSX

Ergonomic Touchscreen

The FLIR E40 touchscreen incorporates the latest FLIR Dark Precision touchscreen technology. This intuitive interface takes advantage of the camera's full 3.5” LCD display and allows you to instantly tap into multiple temperature measurement tools, image modes, archived JPEGs, and more. FLIR's new Auto Orientation feature lets you switch between landscape and portrait views at any time while keeping temperature measurement and other overlays upright.

FLIR Tools Mobile Wi-Fi App

With the free FLIR Tools Mobile app, the E40 can connect to smartphones and tablets via a wireless connection. With the FLIR Tools Mobile app you have the power to stream live thermal video direct from the camera, import radiometric JPEGs, adjust span and level, change palettes, and add up to 3 measurement spots remotely. When done capturing images, the FLIR Tools Mobile app makes it extremely easy to send out images in professional, simple reports via email.

FLIR MeterLink

FLIR Meterlink technology allows for Bluetooth communication between the E40 thermal camera and a range of MeterLink compatible FLIR and Extech meters, including moisture and clamp meters. With MeterLink, the information collected by these meters is transmitted to the E40 and displayed on the screen next to other data. This data is embedded in thermal images when saving and can be extremely useful in analyzing the environmental or electrical conditions associated with a specific thermal event.

Powerful Digital Camera

The FLIR E40 incorporates a 3.1 megapixel digital camera so you can easily capture visible light photos, often essential for reference when examining thermal images. Visible light images can be taken simultaneously with thermal images and then precisely aligned, effectively giving you a thermal and visible light image of the exact same scene. Integrated with the E40's digital camera is an LED light for illuminating dark areas where images must be taken. This LED light also provides extra visible detail in MSX enhanced thermal images.

High-Temperature Range – The FLIR E40 temperature range extends from -4 to 1202°F (-20 to 650°C), giving you the power to measure hotter-running equipment more accurately. This is essential for maintaining safe conditions in industrial applications.

Annotations – The FLIR E40 allows you to easily add voice or text comments to images. This makes inspections more streamlined and saves you time during the image analysis process.

Integrated Laser Pointer – The FLIR E40 features a laser pointer to help users aim the camera more accurately. With the laser, users can pinpoint a reference spot within an image and align a marker to it on screen.

Measuring Modes – The FLIR E40 supports up to 3 spot meters, 3 moveable area boxes with min/max/avg, and Delta T measuring. A fixed picture-in-picture mode with the option to use FLIR MSX is also available.

Accessories – The FLIR E40 standard lens features a 25 degree field of view, with 15 degree telephoto and 45 degree wide angle options available. A dual bay charger with a spare battery is also available, which drastically extends operating time for the E40.

Q & A

Q:) How does the E40 compare to the other cameras in the FLIR Exx series?
A:) The E40 is a mid-range model in the FLIR Exx series. It is not as powerful as the top cameras in the series, but a more affordable price reflects this difference. Unique features for the E40 include 160 x 120 IR resolution, fixed picture-in-picture mode, 2x continuous digital zoom, and 0.07°C thermal sensitivity.

Q:) Will this thermal camera let me know if water is definitely present in a wall?
A:) No, it will not tell you if the anomaly that you are seeing is water. However, if water is present, the camera is going to show that there is some activity in that spot. In order to determine if it is moisture we always recommend purchasing a moisture meter. Certain MeterLink-enabled FLIR and Extech moisture meters are able to transmit data to the E40 via a Bluetooth connection.

Q:) Can you purchase additional lenses for the FLIR E40?
A:) Yes! FLIR has additional lenses available for this cameras. A 25 degree lens is included with purchase. A wide angle 45 degree lens and a 15 degree telephoto lens are available to expand the E40's capabilities.

Q:) What is the benefit of an integrated laser pointer?
A:) A laser pointer can help you aim your thermal camera more precisely. On FLIR cameras, when you select a reference point with the laser pointer, you can then align a marker to it on the image for precise detection.

Q: What is the difference between the E8 and the E40?
A: There are several. Visit our E8 vs E40 Comparison Page
