Hydration Probe; Elasticity Probe; Skin Temperature Probe; Skin Ph Probe - Cortexa Technology DermaLab Mini Instructions For Use Manual

•
The temperature and humidity at the skin surface is calculated based on the vapor gra-
dient inside the measurement chamber.

21.4 Hydration Probe

The hydration probe measures the hydration level of the stratum corneum down to around
15 micrometers using the conductance method.
• Two variants: Flat faced or pin electrodes
• Conductance: 0 – 9999 µS (1 µS resolution).
• Measurement frequency: 100 kHz for hydration flat and 300 kHz for hydration pin.
• 1 second measurement time
• Factory calibrated and linearized within the entire measurement range.
• Optional calibration checker available.
• Measurement uncertainty: ±5%

21.5 Elasticity Probe

The elasticity probe utilizes a well-established method to evaluate the (visco)-elastic proper-
ties of the skin using controlled mechanical deformation. The measured elevation/retraction
curves provide information about skin aging and the collagen/elastin content of the skin.
• Measurement of air pressure-induced skin elevation and subsequent retraction time.
• Settings: Adjustable pressure (150, 400, and 650 mbar) and skin thickness (in mm).
• Measurements: Young's Modulus, Retraction Time, and Viscoelasticity.
• 10 mm diameter suction area.
• Ultra-low weight (approx. 7 grams) for minimum measurement bias.
• Adheres to the skin by double sided adhesive tape.

Skin Temperature Probe

21.6
• Range: 0 – 50 ˚C/ 32 – 122 ˚F.
• Measurement uncertainty: ±0.1° (36°-39° at 20°-30° ambient temperature)
• Resolution: 0.1 ˚C.
• Display Mode: Degree Celsius or degree Fahrenheit.

21.7 Skin pH Probe

• Probe type: Standard gel-filled surface type probe.
• Range: 1.00 – 11.00 pH.
• Calibration liquids included (4 and 7 pH)

21.8 Dermascope Probe

Handheld digital microscope
• Readout: Digital image 1.3M pixels (SXGA).
• Magnification: 10x-50x
• Save format: jpeg.
• Illumination: 8 x white LED.
• Selection between diffused and polarized light source.
• Medical Device Class 1 – Medical Devices Regulation (EU) 2017/745

21.9 Sebum Strip Reader

• Principle: Optical assessment of collected sample.
• Sebum collector: Microporous polymer film mounted on light absorbing substrate.
• Sebum score: 0 – 99.
