Configured with the 29 mm focal-length lens, it delivers a 14° × 10° field of view and a 0.52 mrad/pixel spatial resolution (IFOV), making it suited to thermography work where the target is at a distance and finer angular detail per pixel is required. The camera pairs the infrared sensor with a 5 MP visible-light digital camera and FLIR's MSX image enhancement, presenting results on a 4-inch optically bonded PCAP touchscreen with an additional viewfinder for use in bright outdoor conditions. Thermal imaging cameras in this class are used to visualize surface temperature distribution non-contact across a wide range of inspection and diagnostic tasks. The T840 supports thermographic measurement across three camera temperature ranges spanning –20°C to +1500°C, with measurement accuracy specified at ±2°C or ±2% (whichever is greater) for ambient conditions of +15 to +35°C. Onboard measurement tools include up to three spotmeters and three area measurements in live mode, automatic hot/cold detection within an area, emissivity correction from 0.01 to 1.0, reference and difference temperature functions, and external optics/windows correction. A 0.5°C accuracy screening mode at 37°C with reference is also specified. ValueTronics International stocks, inspects, and ships thermal imaging instruments such as the FLIR T840 from a 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Each {{CONDITION}} unit moves through documented inbound receiving, technician inspection, and functional verification before it is offered for sale, and every order ships from the same Elgin facility where it was inspected. Working directly with a domestic specialist eliminates the drop-shipping pass-through model used by many online resellers and gives engineers, calibration labs, and procurement teams a single accountable source for the instrument, its accessories, and its post-sale support. ## Brand Heritage FLIR Systems is a long-established thermal imaging manufacturer; in 2021 FLIR became part of Teledyne Technologies, and current products are issued under the Teledyne FLIR brand. The T840 datasheet referenced here was published by FLIR Systems, Inc. and the product, accessories, and documentation continue under the combined Teledyne FLIR organization. ## Accessories Supplied - Accessory box I: Power supply for battery charger; Power supply, 15 W/3 A; Printed documentation; SD card (8 GB); USB 2.0 A to USB Type-C cable; USB Type-C to HDMI and PD adapter; USB Type-C to USB Type-C cable (USB 2.0 standard) - Accessory box II: Lens cap strap; Lens cleaning cloth; Neck strap; Small eyecup - Battery (2 ea) - Battery charger - FLIR Tools+ license card - Hard transport case - Infrared camera with lens - Lens cap, front - Lens cap, front and rear (only for extra lenses) ## Product Core & Specifications Imaging and Optical Data Infrared Resolution 464 × 348 pixels UltraMax (super-resolution) In FLIR Tools (not supported when using macro) NETD <50 mK @ +30°C (+86°F) Field of View 14° × 10° Minimum Focus Distance 1.0 m (3.28 ft.)

The laser distance meter is a Class 2 device operating from 0.05 to 40 m. Activate only via the dedicated button and observe standard Class 2 laser safety practices.**Important:** The 6° lens (T300095) requires service calibration when installed.**Important:** UltraMax (super-resolution) is not supported when using macro mode.**Important:** WLAN 5 GHz frequency band 5150–5350 MHz is for indoor use only; see national regulations.**Important:** Charging temperature range for the Korean market is restricted to +10°C to +45°C (+50°F to +113°F).Recommended pairing: the FLIR T840 communicates over Bluetooth with FLIR meters supporting METERLiNK, allowing measurement values from a compatible FLIR meter to be embedded directly into the thermal image. The Bluetooth headset accessory (T197771ACC) is also listed for voice annotation work. **Please review the Manufacturer's Data Sheet to verify published specifications.
