The UNI-T UTi740H+ is a manual-focus handheld thermal camera built for industrial and building professionals who need both resolution and reach.

A 400×300 infrared detector pairs with a <35mK thermal sensitivity rating to resolve fine temperature differences, and Super Resolution lifts captured images to 800×600 for sharper detail in reports. The 4.3″ capacitive touchscreen (800×480) makes menu navigation and on-screen measurement quick in the field.

A manual focus ring lets the UTi740H+ sharpen on both near and distant targets — the difference between a usable measurement and a blurred frame when shooting a panel across a room or a connector at the top of a pole. Measurements save as radiometric photos or video, and Wi-Fi connectivity streams live or transfers files to the PC and mobile analysis software. IP54 sealing and a 2-meter drop rating handle job-site conditions, and the detachable 5200 mAh battery swaps in seconds.

UNI-T UTi740H+ Details

Manual Focus Ring for Distance Inspections

The UTi740H+'s manual focus ring is the feature that separates it from point-and-shoot thermal cameras. Bringing a distant target into sharp focus — a busbar across a substation yard, a connector at the top of a pole, a roof-mounted unit from ground level — is what makes the measurement trustworthy. A defocused thermal image does not just look soft; it averages temperature across pixels and understates a real hotspot.

T-Mix Fusion Overlay

T-Mix fusion blends the thermal image with the 5 MP visible-light camera so a hotspot is shown in the context of the equipment around it. Instead of a floating orange blob, the operator sees which specific terminal, bearing, or pipe is running hot — which makes the captured image far more useful in a report handed to someone who was not on site.

Full Analyzer Toolkit + Isotherm + Hi/Lo Tracking

On-screen measurement covers 16 points, 16 lines, 16 rectangles, and 16 circles simultaneously — enough to document an entire panel of terminals in one frame. Hi/Lo temperature tracking automatically marks the hottest and coldest pixels in the scene, and the Hi/Lo alarm flags any reading past a preset threshold with an on-screen animation and buzzer. Five isotherm modes (Auto, Manual, Above, Below, Section) paint a chosen temperature band in contrasting color.

High-Resolution IPS Touch Display

The 4.3-inch capacitive touchscreen runs at 800×480, so menus, measurement tools, and the live image are all driven by tap and swipe rather than button-stepping. For a technician working in gloves on a ladder, direct touch on a large bright panel is faster than navigating a keypad.

Radiometric Video and Wi-Fi Live Streaming

The UTi740H+ records radiometric video in MP4 and UIR formats — the UIR file keeps full per-pixel temperature data, so a recorded heating or cooling event can be analyzed frame by frame afterward. Wi-Fi live streaming sends the view to a phone, tablet, or PC in real time, useful for showing a second person the scene or recording a walk-through to the analysis software.

Detachable Battery and Field Ruggedness

The 5200 mAh lithium-ion pack is detachable and charges over USB Type-C, giving approximately 4 hours of continuous runtime with Wi-Fi off; a spare pack extends that to a full shift. An IP54 rating protects against dust and splashing water, and the 2-meter drop spec covers the falls that happen on real job sites.

Choosing Your Model: UTi740H+ vs. the H+ / 760H Enhanced Series

The UTi740H+ and UTi760H share the same chassis, <35mK sensitivity, manual-focus optics, 4.3″ touchscreen, 16-point analyzer, radiometric video, and 30 Hz frame rate. They differ in one thing that matters most: detector resolution. More pixels mean finer thermal detail and the ability to measure smaller targets at a given distance. The matrix below shows the difference.
