The Loresta GX is used to measure conductors and semiconductors in the lower resistance range. Measuring range: 10^-4 – 10^7 Ω. It is used to measure the surface resistivity (Ω / □), the volume resistivity (Ω · cm), electrical conductivity (S / cm) in the low-resistance range. The Loresta-GX works according to the 4-pin measuring method. The method is based on the four-wire method and was developed to eliminate the influence of contact resistance. The measuring heads consist of four needle-like electrodes. To simplify the measurement method and calculate the correction factors, all four electrodes are at an equidistant distance from each other. Conductive Materials: Paints, pastes, paints, printing ink, Smart Textiles, Plastics, rubber Film materials, metallic thin films, metallised films, resistor pastes amorphous silicon / silicon wafer, antistatic materials, EMC shielding materials ...

Prior to coating plastic workpieces, they can be flame heated using a gas burner to improve adherence. This is not a heat treatment but rather a selective utilisation of the chemical effect of the gas flame. Naturally, we also offer further pretreatment equipment, such as the plasma treatment for example. During flame heating, the surface is briefly subjected to the direct effect of a gas flame fed with extra oxygen. This causes the breaking of molecular bonds in the surface of the substrate to be treated, and the binding of active ions, mainly OH and COOH groups existing in the flame. In this manner, polar groups, enabling the secure bonding of printing inks, lacquers/paints, adhesives, etc. are created in the originally nonpolar material. Due to the formation of polar groups, the surface energy of the treated substrate increases to a measurable amount.
