Surface inspection and gloss measurement

Welcome to Sensor Instruments
"Surface inspection and gloss measurement"

Do you need to perform gloss measurement, turbidity inspections or contrast or structure inspections? Then you have come to the right place! We provide various inline sensors for each measurement procedure:

The gloss detection sensors of out GLOSS series provide three different angle types (20°, 60° and 85°) depending on the degree of roughness of the surface to be measured.

Should you need to differentiate exactly between various interior components from the automobile sector, starting with a range of different-colored and structured leather and synthetic leathers, textiles and ultrasuedes, the COLOR GLOSS CONTRAST NIR sensors of the COAST series do just the job.

The haze plays an important role in ascertaining the surface quality of stainless steel and aluminum sheets. The sensors of the GLAST series can determine the quality of these metal surfaces with great precisions. Various graticules are available for these sensor types.

The SI-JET series allow you to keep the spraying procedure under control. Ranging from spray jets invisible to the eye to highly-dosed jets or targeted metering (individual droplets) delivered via a piezo nozzle, the SI Jet series is fitted with the matching sensors.

The SPECTRO-M series reveals the mid-wavelength infrared light range, permitting for example, the detection of thin oil layers or the ascertainment of the thickness of transparent, extremely thin films.
A further advantage: our sensors permit the highly-precise inline detection of your products even in challenging environments.
