Ultraportable digital glossmeter

The appearance of your product’s surface—no matter the material—determines its attractiveness, influences its functionality and conveys its premium value by showcasing the quality of your operations to customers. As a result, surface gloss and haze are product attributes that are precisely specified and tightly controlled along a supply chain—from the initial coating application, to showroom, to after-market refurbishment.

Zehntner ZG8000 by Proceq enables coating suppliers, product manufacturers and quality inspectors to do exactly that— inspect the quality – easily and effortlessly. The rugged, lightweight, ergonomic probe packs Swiss Made optics and electronics, paired with sophisticated Stray Light Compensation algorithms and a rich set of features. Connect the probe wirelessly to your mobile device and enjoy our user-friendly app with insightful statistics, sharing, collaboration and reporting – anywhere, anytime.

Feature-rich and user-friendly

Zehntner ZG8000 is the only glossmeter in the market that offers such a wide range of features and measuring modes in a lightweight, ultraportable probe. The small measurement footprint together with the thin side-profile of the probe make even the tightest spots and the smallest curved surfaces easily accessible.

With four different measurement modes, all applications can be tackled—from the smallest curved parts requiring spot checks, to the largest surfaces requiring hundreds of measurement points. On the probe itself, this rich feature set and settings can be accessed with only two buttons that control the intuitive menus with a clear structure.

A versatile probe, focused on you

The Zehntner ZG8000 probe has been designed from the ground up to bring comfort to gloss testing processes, no matter the surface being tested or the environment it is tested in.

The brushed-aluminum casing features an ergonomically-placed measurement button so that you can use the probe confidently and without any unsteadiness, on all kinds of surfaces and in different orientations. The crystal-clear OLED screen with wide viewing angles delivers visibility under all conditions and also features a sharp resolution and contrast for readability of results. The probe is powered by an off-the-shelf, flight-safe AAA battery that can be recharged rapidly over USB. For measuring sensitive surfaces or curved parts with stability and without risk of surface damage, different rubber attachments are also available. The built-in targeting laser can be used together with the side-view of the measuring spot to make positioning accurate.

Optical technology with intelligent algorithms

At the heart of Zehntner ZG8000 is a high-quality optical assembly, built upon 50+ years of Swiss Made expertise in optical instrumentation, combined with a long history of successful glossmeters from the Zehntner brand.

Despite its pocket size, the Zehntner ZG8000 probe features a standards-compliant two-angle geometry for measuring high-gloss and mid-gloss surfaces at 20° and 60° of light incidence with high accuracy and repeatability. This also makes it possible to measure unwanted haze, i.e. the degree of reflection from inside a highly-reflective coating.

Traditional glossmeters have long suffered from measurement inaccuracies that are caused by stray light from natural or artificial light sources – such as from the sun or the subtle strobe effect of overhead halogen lights. However, the Zehntner ZG8000 features Stray Light Compensation – intelligent algorithms monitor the environment for stray light and utilize this information to exclude deviations, so that you can measure with high accuracy and peace of mind – anywhere, anytime.
