IR thermometer uses visible light camera
-- Test & Measurement World, 10/1/2008
The Extech/FLIR i40, i50, and i60 infrared thermometers feature a visible-light camera that lets you see the target and point the instrument. The i40 has a 0.6-Mpixel camera, while the i50 and i60 have 2.3-Mpixel cameras. All models feature a picture-in-picture display with fixed (i40), three-step (i50), or scalable (i60) images on a 3.5-in. LCD. With the i40, you can view the target image; the i50 and i60 include a semiconductor laser target, and the i60 is able to display the laser on the screen. The instruments can also find the hottest or coldest spot within a designated area and mark that area.
Temperature range on all three models is –20°C to 350°C (–4°F to 662°F) with 2% accuracy and 0.1°C thermal resolution. All models include a 1-Gbyte SD storage card that can store up to 1000 jpg images. The thermometers can run up to 5 hr on a rechargeable lithium-ion battery.
