Thermal Imager GUIDE TD433L

GUIDE TD433L – One-handed operation, LRF and top thermal imaging in a compact form


The GUIDE The TD433L from the TD Gen3 LRF series combines innovative technology with a particularly handy design. Thanks to the focus wheel, you can comfortably operate the device with one hand. The symmetrical housing is ergonomically shaped and allows for flexible use with either the left or right hand.


Highly sensitive detector for razor-sharp images Equipped with a 12 µm infrared detector and a resolution of 400 × 300 pixels, the TD433L delivers impressively detailed images. The 35 mm lens enables clear vision – even in complete darkness. Thanks to a NETD value of ≤ 25 mK, even the smallest temperature differences become visible.


Focus in no time The top-mounted mini focus wheel allows for quick and precise focus adjustment—without having to reach up to the front of the lens. All important functions can be operated with one hand, regardless of whether you're right- or left-handed. This keeps one hand free at all times.


AMOLED display for more details The GUIDE The TD433L features a 0,36-inch AMOLED display with a resolution of 1280 × 960. This high-resolution display delivers a high-contrast, detailed image while ensuring a comfortable viewing experience—ideal for long observations.


Integrated rangefinder For precise distance measurement, a rangefinder (LRF) is seamlessly integrated into the device. With a range of up to 1000 meters, you can reliably determine the distance – compact, practical, and ready for use at any time.


Long-lasting battery The GUIDE The TD433L is equipped with a replaceable 18650 battery that reliably accompanies you even during extended missions. Changing the battery is quick and easy – even in the dark.

Intelligent recording and storage Capture your observations: With the Smart Recording feature, you can record videos with audio. The built-in 32 GB memory offers space for more than 100.000 images—enough to capture your experiences at any time.


Robust and reliable With an IP67 rating, the TD433L is well-equipped to withstand dust and rain. Combined with its long battery life and Wi-Fi functionality for easy connectivity, it's a versatile companion for all outdoor adventures.
