Request InfoHohner Corp.Hohner Corp. offers a pen-size roughness sensor for use as a quality control tool for in situ inspection of surface roughness. This noncontact device has no stylus tip, which makes it suitable for metals and soft materials such as paper, ceramics and paint. A measurement range of up to 100 relative units can be translated into absolute roughness values. The compact handheld device is approximately 4 in. long and comes with a Universal Serial Bus interface, drivers for Windows 98, standard application software and a Dynamic Link Library unit for data acquisition.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 8/3/2022Two-color Sandwich DetectorsTwo-color Sandwich Detectors from OSI Optoelectronics Inc. are designed for optical remote temperature measurements.
