Fluke Ti401 PRO 640 x 480 Infrared Camera
Description
Ti401 PRO 640 x 480 infrared camera with LaserSharp focus
The Fluke Ti401 PRO is a pistol-grip thermal imager for industrial maintenance teams who need a full 640 x 480 detector without paying for the extra functions of the top-of-range models. It sits at the entry point of the PRO series, below the Ti480 PRO, and is built around the same optics, the same laser-assisted focus and the same wireless workflow. Seven Star LLC supplies the Ti401 PRO in Oman and the GCC as an independent supplier in Muscat, not affiliated with the manufacturer.
The model name is simple, but the ordering information adds one choice that matters: the camera is listed in a 60 Hz version and a 9 Hz version. Both use the same 307,200-pixel detector; the frame rate is the only difference listed in the datasheet.

How the Ti401 PRO produces a focused, measurable image
A thermal image is only useful if the target is in focus, because defocus averages the temperature of a hot connection with its cool surroundings and understates the fault. The Ti401 PRO addresses this with a laser distance meter that measures the range to the point you aim at and drives the lens to the matching focus position. The distance is shown on screen, which also helps when the same inspection route is repeated months later from the same standing position.
The detector registers long-wave infrared between 7.5 µm and 14 µm. The camera converts radiation to temperature using on-screen corrections for emissivity (value or material table), reflected background temperature and transmission, so that bare copper, painted steel and insulating covers can each be set up correctly. IR-Fusion blends the 5 MP visible image with the thermal image so that a hot spot can be tied to a recognisable component, label or terminal.
Where the Ti401 PRO fits in the Fluke thermal range
The Ti401 PRO shares its 640 x 480 detector with the Ti480 PRO, TiX501 and TiX580. What changes between them is the feature set. Compared with the Ti480 PRO and TiX580, the Ti401 PRO has no digital zoom, no video recording, no line temperature graph, no auto capture and no user-definable spot markers, and its measurement ceiling is 650 °C rather than 1,000 °C. In return it is the lightest of the group at 1.04 kg and keeps the one-handed pistol-grip form. The cameras below the PRO line, such as the Ti300+ at 320 x 240 and the TiS series, use smaller detectors.
| Model | Detector | Max range | Display | Digital zoom | NETD |
|---|---|---|---|---|---|
| Ti401 PRO | 640 x 480 | 650 °C | 3.5 in | No | 75 mK |
| Ti480 PRO | 640 x 480 | 1,000 °C | 3.5 in | Yes, 2x and 4x | 50 mK |
| TiX501 | 640 x 480 | 650 °C | 5.7 in articulating | Yes, 2x | 75 mK |
| TiX580 | 640 x 480 | 1,000 °C | 5.7 in articulating | Yes, 2x/4x/8x | 50 mK |
Selecting the Ti401 PRO and its accessories
- Confirm that a 650 °C ceiling covers your hottest target; furnace, kiln or steam-line work may need a 1,000 °C model.
- Choose 60 Hz when you scan moving or vibrating machinery; a 9 Hz version is available where the frame rate is not needed.
- Decide on lenses: the optional 2x telephoto, 4x telephoto, wide-angle and 25 micron macro Smart Lenses need no calibration after fitting.
- Plan spare batteries; each pack gives 2 to 3 hours, and the two-bay charger shortens turnaround.
- Check software needs: the free desktop software exports to BMP, GIF, JPEG, PNG and TIFF.
Installation, commissioning and maintenance of the Ti401 PRO
The Ti401 PRO needs no installation. On first use set the language, date, emissivity default and temperature unit, and insert the micro SD card. Charge both batteries before the first inspection, because smart batteries show their state of charge on a five-segment display. The manufacturer recommends a two-year calibration cycle under normal operation, so plan a verification before the second year if the images feed compliance records. Keep the germanium lens clean with a soft cloth and lens-safe solution only; abrasive wiping damages the coating. Store the camera in the supplied hard case with the batteries removed if it will sit unused for long periods.
Operating temperature is -10 °C to +50 °C. In summer plant areas of the Gulf, a camera left in a vehicle can exceed that limit, so keep it in the cab or in shade and let it settle before use.
Typical applications of the Ti401 PRO in Oman and the GCC
In oil and gas facilities the camera is used to scan motor control centres, switchgear, transformer bushings and cable terminations while equipment is loaded. In power and desalination plants it finds hot bearings, overloaded phases and blocked heat exchanger passes. Petrochemical sites use it to check insulation damage on hot piping and refractory condition on small heaters within the 650 °C range. In hot, dusty and humid conditions the IP54 enclosure and removable memory card keep the routine simple, and the laser-assisted focus lets inspectors keep a safe distance from live panels.

Several of the bench models belong to earlier generations. When a model is no longer produced, we check the manufacturer's documentation and propose the successor it names.
Where Fluke instruments are used
Fluke process calibrators are used for loop checks, transmitter calibration and valve tests in oil and gas, power and water plants. Clamp meters and insulation testers serve electrical maintenance on motors, switchgear and cables. The bench calibrators and reference multimeters are the working standards of electrical calibration laboratories in the GCC, where they calibrate multimeters, clamp meters, process tools and power analyzers.
Fluke products we list
Ordering Fluke instruments: what we need
Send the exact model with its suffix, since versions differ. A Fluke 721, for example, is defined by its two pressure ranges, and a 729 by its maximum pressure. For bench calibrators, list the options you need, such as oscilloscope calibration or power quality options, the line voltage, and the type of calibration certificate you require from the manufacturer. For Fluke multimeters and clamp meters, add the kit contents wanted, such as probes, leads or cases.
