Product Details

FLIR DM285 Thermal Imaging Multimeter

The FLIR DM285 Thermal Imaging Multimeter is a handy combination of a thermal imager and an advanced electrical measurement instrument with additional wireless and datalogging features. It can measure AC/DC voltage (1000V), AC/DC current (10A), resistance (50MΩ), capacitance (10mF) and frequency (100kHz) with further options for continuity and diode testing. It is also compatible with a type K thermocouple to measure temperature from -40˚C to 400˚C whilst a µA range can test flame sensors. The multimeter also boasts True RMS, LoZ voltage measurement and a VFD voltage measurement function.

The 160 x 120 pixel thermal sensor provides sharp thermal images by measuring temperature between -10˚C to 150˚C with ±3˚C accuracy. Thermal sensitivity of ≤150mK means that small temperature differences (0.15˚C) can be depicted on screen and the 50˚ x 38˚ field of view allows sharp focus at very short distances. Fixed focus and automatic ranging ensures that the FLIR DM285 provides the user with clear, useful thermal image.

The vibrant 2.8” colour screen shows thermal images in one of three palettes (iron, rainbow, greyscale) and provides the user with a digital temperature read out as well as a range indication. It has a wide angle design that can be viewed very easily and there is also min/max/average recording and a useful data hold function. Ranging is usually automatic but the user can take manual control if needed. The function is selected by the clearly-labelled dial and it is easy to navigate the intuitive onboard menu.

One of the standout features of the FLIR DM285 is the large internal memory that has enough room for up to 40,000 readings as well as 100 saved thermal images. The Bluetooth connectivity allows the multimeter to wirelessly communicate with the FLIR Tools Mobile app on smartphones, thus permitting rapid dissemination of inspection results. It is also compatible with the FLIR InSite™ workflow management tool which streamlines analysis and reporting.

The FLIR DM285 is rated as Cat III 1000V, Cat IV 600V and has a non-contact voltage detection function which alerts the user to live conductors. The ergonomic design makes the multimeter easy to use in tricky conditions and it has built in work lights to illuminate the working area in poor visibility. It comes supplied with a battery, silicone test leads, a type K thermocouple, crocodile clips and a soft carry case.
