Testo's 875i thermal imager helps improve predictive maintenance

Testo's 875i thermal imager is built to offer high thermal sensitivity, high image quality, and simplified ease of use. Centered around the thermal sensitivity of < 50 mK, and the image quality of 160 x 120 pixels, which can be increased to 320 x 240 pixels with the SuperResolution technology, small details and slight temperature differences can be identified with the Testo 875i.

Testo 875i offers the possibility of recording thermographic images with the SuperResolution technology. SuperResolution adds additional real measurement values to the recorded image, resulting in a (4X) four-time increase in pixel resolution and added benefit of improved geometric resolution by a factor of 1.6.

The thermal images are visualized in real time on a 3.5-inch display. Critical temperatures and hot-cold spots can be displayed directly on the display as well. Verbal notes can be captured by the thermographer and archived directly as part of the image file via a headset for later recall. Image analyses and reports can be carried out on any Windows PC. Image overlay of real and thermal images (TwinPix) is accomplished by using a software wizard built into the PC software.
