Cutometer® Dual MPA 580 - Mechanical Parameters of the Skin What Does It Measure? For many years, the measurement of elasticity parameters with the Cutometer® Dual MPA 580 has been worldwide acknowledged as standard method. The Multi Probe layout allows to connect up to four probes additionally to two Cutometer® probes. A Sebumeter® is also built in. The Measuring Principle The measurement is based on suction. Negative pressure created by a vacuum pump within the device draws the skin into the aperture of the probe. Inside the probe, the penetration depth is determined by a non-contact optical measuring system. It consists of a light source and a light receptor, as well as two prisms facing each other, projecting the light from transmitter to receptor. The light intensity varies due to the penetration depth of the skin. The resistance of the skin to be sucked up by negative pressure (firmness) and its ability to return into its original position (elasticity) are displayed as curves in real time. Fields of Application The measurement with the Cutometer® is used as standard in anti-ageing research and cosmetology. • It is indispensable for formulation, efficacy testing and claim support for all kinds of cosmetic products (esp. anti-ageing products, firmness enhancing & anti-cellulite products). • Basic research of mechanical properties of the skin and skin ageing. • Other materials like food or textiles can also be assessed. Advantages • Several probe aperture sizes (2, 4, 6 and 8 mm 0) for various skin sites and study requirements (e.g. different skin thickness, scars) are available. Two probes with different aperture sizes can be connected at the same time. A spring in the measuring head provides constant pressure on the skin. The convenient handling of the probe permits measurements at all skin sites. The probe head can easily be cleaned after each measurement. A multitude of elasticity related parameters can be calculated from the curves. Intuitive, graphic explanation of the various results. The settings in the programme are very flexible and can be adjusted according to different applications or study layouts. See the live offset at the start of each measurement for the control of pressure when doing comparison measurements. Export the results and curve data of a complete study directly to Excel®. Available solely as C+K MPA system to be operated with the overall MPA CTplus software.
