Keysight U5855A TrueIR Thermal Imager – for temperature measurement up to 350°C

The U5855A is ideal for predictive maintenance activities, from hot spot detection to thermal profiling. With this thermal imager, you get 320×240 Fine Resolution. Ability to magnify the thermal image of a far‑away object by 4 times to reveal finer details and quickly spot problems. Also, take thermal images of close-fit or minute components from as close as 10 cm away clearly and accurately.

The U5855A also comes with a variety of measurement and analysis tools to help you monitor temperature over time, do min and max temperature tracking and more so that you can easily obtain heat patterns, dissipation and etc. The U5855A comes with a built-in quick start tutorial to help you get familiar with thermal imager quickly.

What’s more, with the complimentary TrueIR Analysis and Reporting Tool, you can easily import, analyze and edit thermal images and quickly generate reports using ready templates. You can also display thermal images, visual images or thermal-visual images side-by-side for further analysis.
