UNI-T UTi120S Handheld Thermal Imaging Camera, 120×90, -4 to 752°F

Product details

The UNI-T UTi120S is a simple, tough handheld thermal camera for fault finding and temperature checks. It has a 120×90 infrared sensor, a focus-free lens, a 2.4-inch screen, 16 GB of storage and a battery that runs for about 9 hours, in an IP54 body that survives 2 m drops.

What the specs mean in practice

Resolution. 120×90 gives 10,800 thermal pixels. That is enough to locate a hot connection, a cold pipe or a leaking section of wall, but fine detail on small parts looks blocky.

Focus free. A fixed-focus lens means no adjustment on the job. You point, look and move on, which speeds up routine walk-around checks.

Battery and storage. A battery rated for about 9 hours and a 16 GB card cover a full shift of inspections without stopping to offload images.

What you can use it for

• Maintenance rounds: scan motors, bearings, panels and belts for abnormal heat.
• Heating checks: verify radiators, floor loops and boilers.
• Electrical: check breakers, fuses and connections up to 400°C.
• Alarm-based screening: set a high temperature limit and let the camera flag anything above it.

Who should look elsewhere

• You need to see hot surfaces above 400°C. See the UNI-T UTi260B (550°C).
• You need fine detail on small circuit boards. Choose a 256×192 model.

How it compares

• HTI HT-03: the same 120×90 class with a 550°C range and a built-in visible camera.
• MILESEEY TR10: 192×192 sensor with a wide 50° field of view.

Tips for better results

• Scan electrical equipment under normal load and compare like with like.
• Shiny bare metal reads cooler than it really is. Measure a patch of black electrical tape instead.
• Glass blocks thermal imaging, so you see the glass surface and not what is behind it.
• Use the high and low temperature alarms to flag problems quickly on repeat inspections.

Frequently asked questions

What does 120×90 mean in practice?
The sensor has 10,800 thermal pixels. That is enough to locate hot spots on panels, pipes and walls, but it shows less fine detail than 256×192 cameras.

Do I need to focus it?
No. The lens is fixed focus, so you point and scan.

Can I analyze images on a computer?
Yes. PC analysis software is supported over USB-C.

How long does the battery last?
Around 9 hours of use on a full charge.

How tough is it?
IP54 against dust and splashes, with 2 m drop resistance.

Best-fit applications

Home maintenance, HVAC checks and electrical troubleshooting. Check the native sensor resolution, lens and device compatibility to decide whether this model fits your intended working distance and target size.

Before you buy

Review the specifications above and confirm compatibility with your equipment. Image enhancement is not the same as native infrared sensor resolution. Contact ThermalVisionPlus if you need help comparing models.
