Handheld thermal imaging camera, affordable, rugged and easy to use
Inspecting transformation centres and electrical switchgear on a tight budget calls for a rugged, simple radiometric handheld camera with a 384x288 detector, good thermal sensitivity and simultaneous multi-point measurement. The IRDL700 offers this with an uncooled 384x288 FPA microbolometer, 0.88 mrad spatial resolution, thermal sensitivity of 0.06 °C or better at 30 °C and a -20 °C to +500 °C range extendable to 1200 °C or 2000 °C, with up to 10 movable points and 5 movable areas, a laser pointer and single-button operation.

About the product
The body integrates a 300,000-pixel visible-light camera, a class 2 laser pointer (1 mW at 635 nm) to mark the measurement point, and optional wide-angle and telephoto lenses that widen or narrow the standard 16 by 12 degree field of view. Images, with 14-bit thermal data, are stored on the built-in flash memory or a 2 GB SD card, together with voice notes of up to 40 seconds, and are transferred to a PC via USB for analysis and inspection report generation.
It runs on a rechargeable Li-Ion battery, with 2 hours of continuous operation, an intelligent charger or optional power adaptor, and works between -15 °C and +50 °C with IP54 protection.
