Thermal Imager
Data Sheet
Reap the benefits of a high resolution thermal imager that fits within your
available budget. With the Fine Resolution capability, you can achieve
effective resolution of 320 x 240 pixels from a 160 x 120 pixels detector –
four times more resolution, four times more details.
• Four times more pixels with Fine Resolution capability
• View finer object details with 4x digital zoom
• Quick access buttons to easily change settings or functions
• Long product warranty – 3 years
• Ergonomically designed with evenly distributed weight
• In-camera monitoring for temperature trending
• Ability to focus on objects, as close as 10 cm away

Get more details with Fine Resolution
Fine Resolution is a technology that restores the details originally
inherent to the object while enhancing the resolution, at the
same time minimizing fuzziness and noise. It is accomplished by
performing sophisticated calculations on continuous multi-frames
of the image – evaluated for misalignment caused mainly by hand
tremor. The firmware then detects and corrects the information
between images through one feature pixel.
With Fine Resolution,
• Get an effective 320 x 240 pixels of radiometric JPEG IR image
which is clearer and sharper
• See fine details on objects as close as 10cm, especially when
measuring temperature on small components which are close to
each other.
• With 4x digital zoom, magnify a thermal image of a far-away
objects quickly to identify anomalies and to reveal even finer
details.
• These are essential for industrial, building inspection, electronics,
as well as medical research.

Perform more in-camera measurements
and analysis
Capture thermal images effectively with its intuitive and easy to
use tools:
• Configurable quick access buttons that are able to change
functions based on user preference.
• Monitor temperature trends over time for quality checks when
monitoring process parameters in industrial plant automation
• Perform analysis using its extensive range of measurement tools.
• Coupled with the U5855A’s high sensitivity of 0.07 °C, it can
detect the slightest temperature difference to provide more
accurate temperature readings.

TrueIR Analysis and Reporting Tool
Import, analyze, edit and present your thermal images to your
clients swiftly with TrueIR analysis and reporting tool. With this PC
software, you could change color settings and corrective parameters,
add color alarm, or pick and choose any of the six measurement
analysis tools or diagrams to help you present your findings to your
customers clearly.
Also, generate reports quickly with the help of ready templates
and then customize them accordingly based on your clients’
requirements.
Features:
• Change color settings and corrective parameters, like emissivity,
ambient temperature, atmospheric temperature, and more
• Set color alarm
• Choose between six measurement analysis tools or diagrams like
spot, line, line profile, box, histogram and delta temperature
• Capable to display thermal image, visual image, thermal-visual
side-by-side, or fusion images as well as its associated photo or
note tags
• Create reports based on available templates and then customize
them to suit your client’ needs
• Generate reports in Microsoft Words or PDF
• Eleven local languages to choose from - English, Spanish, Italian,
French, German, Portuguese, simplified Chinese, traditional
Chinese, Japanese, Korean and Russian
