Karlak UTi260A Professional 256 x 192 IR Thermal Imaging Camera Rechargeable Handheld Temperature Car Tracking Infrared Thermal Imaging Camera with 2.8 Inch LCD Screen, Real-time Image Transmission, 7

Product Information

The 260K seems to be targeted to fever scanning as Unix5566 mentioned, so I am hoping the price premium is mostly due to the increased sensitivity and the current demand. Reliable Quality, IP65 Rating]-- Made of high quality material and is ergonomically designed, with wear resistant and durable shell, anti-slip handle, comfortable operating buttons and tripod mounting hole in the bottom. And with IP65 protection grade and 2m drop resistant, it's more convenient to use for various applications. Obviously, having digital camera and larger measuring range are the pros of UTI260B. But I chose the 260A for saving money because I always prefer the thermal mode rather than the fusion mode, and maybe simpler could be better. It is not easy to find out except to ask UNI-T what the physical resolution of the microbolometer is. Manufacturers sometime obscure that information deliberately.

The camera also has quite a wide viewing angle of 56 x 42 degrees, this is also known as field of view. Then there is the temperature range and things look fantastic here since the sensor can measure any temperature between -5 F to 1022 F (-15 C to 550 C), a range which is about 30% wider than what you would expect from other thermal cameras in this price range. Its thermal accuracy is on par with what’s expected out of thermal sensors these days, +/- 2 C. The PC application works well but is very limited in its use and is limited to a dynamic mirroring of the camera screen. Whilst dead pixel concealment is very effective, in applications where EVERY pixel output is being analysed, such as in some science applications, it is important for the user to know which pixels are not truly active and their data should be discounted from the results. This is limited to science applications though and not really an issue with general camera use. The boot time is around 20s (mostly there is a progress bar) and the switching between the low and high gain takes also around 20-25s (there is no progress bar here). High gain is -15-150C, low gain 150-550C.Model: UTi260B Industrial Thermal Imager Camera(-15℃ ~550℃) with realtime monitoring function UTi260B is a popular handheld thermal imaging camera for industrial use, measuring temperature from -15℃ to 550℃. It is one of the MOST POPULAR thermal camera at high performance. General Configuration: It may be possible to detect pixels that are bing disguised by image processing by sweeping a thin IR source wire across the FOV and analysing the image output for deformations in the imaged line. Not something I have ever done and a purely theoretical process. There is normally no need to analyse the dead pixel content of an FPA unless an issue arises in the cameras correction process or damage is suspected, such as laser induced pixel distortion etc. What might be surprising was that a 320x240 (76k pixels) gives a perfectly acceptable image with over 1000 dead as long as they are scattered.

If a camera is received and it is displaying dead pixels on its display..... it has suffered pixel failures since original calibration and should be sent for a new NUC and dead pixel map creation. Dead pixels are not truly a “Fault” in terms of a camera containing them..... they are a fact of life that the image processing system is designed to cope with. Secondly, there was a teardown from Fraser where you can see the greatly reduced quality of the inner workings. UTi-260B would appear to have been replaced by the UTi-260K so the discontinued model may be available at a good price, as noted by the OP. Avoiding judgement errors, reducing labor cost, and discovering poor heat dissipation and hidden trouble points.This does indeed work, with any good edge. How easily does depend on the replacement system being used. A Raytheon BST does a simple 'copy next' so produces horizontal lines, some tend to copy down/right, some will do an average of the good neighbours.
