R550 Series

Category: Cameras
Manufacturer: AVIO


The AVIO R550 series features high speed sampling - up to 120Hz (R550Pro model) - the highest speed sampling in the portable VGA class equipment (as of August 2018), a high resolution 1.2MP SR Thermal Image (1280 x 960 pixels) and automatic recording functions.

2 models available depending on your application. The AVIO R550Pro with a temperature range of -40 to +2000°C makes this model ideal for R&D, whilst the R550 with a temperature range of -40 to +650°C is ideal for electrical inspection applications.

*1  Only in the Range 1 at the environmental temperature from 20℃ to 30℃. (In other condition: ±2℃ or ±2%)

*2  Windowing ‘Mode W1(640×240 )’

*3  Windowing ‘Mode W2(640×120 )’

*4  Still image only

*5  This increased resolution results from detecting characteristic within all frames acquired by the SR process and removing such effects as those caused by hand vibration.

*6  For temperature accuracy: 30 cm to infinity

*7  Thermal image only when image transfer speed at 30Hz.

*8  In order to transfer Thermal image movie data by R550 / R550-D, you need to upgrade to "InfReC Analyzer NS9500 Professional" (optional software).
