The Sebumeter® SM 815 is available as stand-alone device, in the Derma Unit SSC 3, or built-in in the MPA systems (please see details in Basic Probe Systems).
The measurement is based on grease spot photometry. The mat tape of the Sebumeter® SM 815 is brought into contact with skin or hair. It becomes transparent according to the sebum on the surface of the measurement area. Then the tape is inserted into the aperture of the device and the transparency is measured by a photocell. The light transmission represents the sebum content.
The Probe (Cartridge)
The measuring head of the cartridge exposes a 64 mm2 measuring section of the mat tape. For a measurement the tape is moved forward by a trigger at the side of the cartridge to expose a new section of tape. The used tape is rewound inside the cartridge. One cartridge can be used for approx. 400 measurements. The scale from 1-0 on the trigger shows how much of the tape is still unused. When exhausted, the cartridge is simply replaced for reasons of hygiene.
There are many fields of application where the sebum content plays a major role.
