Epsilon Model E100 Product Description

The Epsilon (Product Code: E100-01) is a novel instrument for contact imaging of human skin, hair and a wide variety of other soft materials, including animal and plant tissues, waxes, fats, gels, liquids and powders. Its proprietary electronics and signal processing algorithms map the sensor's non-linear signals onto a calibrated scale for measuring properties such as hydration and insensible perspiration. The Epsilon is supplied in a sturdy plastic case illustrated below.

Epsilon E100 in Case

The instrument and its parking stand are illustrated below.

Epsilon on and off the stand

The in-vitro stand, illustrated below, can be used for measurements on isolated soft solids and liquids. It consists of a base for mounting the probe with its sensor surface horizontal and facing upwards. It has two vertical posts for mounting height-adjustable measurement accessories.

Epsilon on In-vitro Stand

The standard in-vitro accessories shown below are machined from pure Acetal. They include hollow donor chambers of 5mm and 8mm internal diameter and a solid pressure plug for studying in-vitro solid materials such as leaves. These slip into the mounting ring of the accessories holder and are retained by the central Nylon thumb screw. There is also a matching lid to minimise evaporation of volatile solvents from the donor chambers.


The software supplied with the instrument has facilities for live image streaming as well as image capture in Snapshot, Burst and Video modes. It saves images in industry-standard formats (tiff & avi) for analysis in third-party image analysis software. Some analysis functions (Region of Interest, Permittivity Histograms, Permittivity Time-series, Permittivity Filter, etc) are included in the standard software and these will evolve in response to user feedback. There are also plans to publish optional analysis modules in the future.

Epsilon Software

The Epsilon is straightforward to use. The instruction material is comprehensive, and support is just an e-mail away. In addition, our optional on-site training, in Chinese, English, French or German, aims to build confidence in a new instrument using a new measurement principle.
