FLIR B250/B335


The choice of the professional thermographer

The FLIR B-Series of portable thermal imaging cameras takes ergonomics, weight and ease-of-use to a new level. Usability is key: our engineers have translated user feedback on comfort and clarity into a series of comprehensive and innovative features. Furthermore, the FLIR B-Series has been specifically developed for building environments.
It contains features like dewpoint and insulation alarms that will make the life of any building thermographer a lot easier.

Up to 320 x 240 pixel resolution
320x240 The B-Series thermal image resolution ranges from 240 x 180 pixels to 320 x 240 pixels.

Camera sensitivity
sensiti The thermal sensitivity in the FLIR B-Series ranges from 70 mK to < 50 mK.

High quality visual camera
visual All models in the FLIR B-Series have an integrated 3.1 Mpixel digital camera. This makes observing and inspecting faster and easier.

Panorama support

Panorama Take images in a sequence and automatically combine them to one large image using the FLIR Software. The images can be shot in vertical or horizontal direction or in a combination of the two.

Measurement range
accurate measurement Temperature measurement range -20°C to +350°C

Interchangeable infrared lenses
lenses The B-Series features a standard 25° lens and optional 6°, 15°, 45° and 90° lenses.

Flexible interfaces
flexibleinterfaces The B-Series is equipped with standard video, USB outputs as well as a removable SD card.

MPEG-4 video 
mpeg4 Create visual and infrared non radiometric MPEG-4 video files.

Radiometric IR video streaming
VIDEO STREAMING 16 bit radiometric IR video can be streamed to a PC (via USB) running the FLIR QuickPlot or FLIR ResearchIR software.

pip-b Create an infrared overlay on your visual image. Scalable, moveable and resizable depending on model.

annotations textvoicesket Text and voice annotations
Text comments can be made from a pre-defined list or using the touch screen. A headset can be connected to make voice annotations.

annotations sketch Sketch annotations
Use the touch screen as pen and paper to add sketch annotations.

Image storage
jpg FLIR uses a non proprietary radiometric JPEG image format that allows for post processing and report writing with Microsoft Word® based FLIR software.

Touch screen

touchscreen 3.5" LCD touch screen plus stylus brings interactivity and user comfort to a new level.

Measurement Modes
measurement modes Measurement spots, area with auto hot/cold spot indication, isotherms, ΔT calculation (depending on model).

Meterlink FLIR MeterLink technology simplifies the work in electrical or building inspections by making it possible to transfer, via Bluetooth®, the data acquired by an Extech clampmeter or multi function moisture meter and psychrometer into the infrared camera. The MeterLink technology saves time and eliminates the risk of erroneous records or notes.


wifi Transfer images wirelessly to a smart phone (iPhone) or tablet PC (iPad). Connect directly to the device or via a local network

Copy to USB
copy Transfer on board images or reports directly from the thermal imaging camera to a USB stick.

Humidity Alarm/Insulation Alarm
alarms The Relative Humidity Alarm alerts you to the areas where there is a risk of condensation. An Insulation Alarm shows the insulation performance of the building structure. By inputting relevant values into the camera the areas that fail to fulfill requirements will appear as colored.
