The Zehntner 1000 series of glossmeters (Gloss Meters) are Proceq's largest and most flexible range, with units suitable for all testing geometries, computer connected measurements, measurement on site or in the workshop and for integration into production lines.

Collect high-density, georeferenced GPR data across wide areas and view the subsurface in 3D as you scan. Choose the GX2 array for SUE and utility mapping, or the GX1 array for structural, bridge and pavement investigations.
Best suited to:
Best suited to:
Recommended array: GX2
Recommended array: GX1
Cover more ground
Collect multiple parallel profiles in one pass instead of uilding a grid line by line.
See results during acquisition
View georeferenced radargrams and time-slice information in the field rather than waiting until the data is returned to the office.
Produce repeatable mapped data
Combine wheel-positioned GPR data with GNSS, project coordinates and survey linework.
Use one platform for two very different applications
Exchange GX1 and GX2 arrays without purchasing two complete cart platforms.
The GX2 transforms the GS9000 into a high-density subsurface utility mapping system. Its 11-channel, low-frequency GPR array captures an 83 cm-wide swath in each pass, helping operators detect and map buried pipes, ducts, cables, voids and other subsurface features. Live georeferenced data lets SUE teams review coverage on site and produce accurate CAD, GIS and project-coordinate deliverables.
1. Plan the survey
Load satellite imagery, CAD information, project coordinates or survey control.
2. Collect dense multichannel data
Survey an approximately 0.82 m-wide swath with 11 channels in each pass.
3. Review data live
Examine radargrams, georeferenced time slices and marked features while still on site.
4. Interpret and digitise
Add points, linework, tags, photographs and field observations.
5. Process and deliver
Merge survey areas, apply processing and export mapped information for the customer’s CAD, GIS or reporting workflow.

The Zehntner ZGM 1130 features a 2.4" touchscreen display, support measurement of gloss ranges from matt to high gloss up to 2'000 GU.
ZGM 1130 can be configured to support a range of testing geometries and measurements:
Touchscreen Display for all Gloss Ranges
The display is switchable for either a left-handed or right-handed user. Our precision milled monoblock optic ensures stable and reliable gloss measurements. This glossmeter's powerful stray light compensation allows exact measurements of transparent objects. It also features automatic calculation of "reflection haze H" with our dual and triple angle versions.
Direct Access to Measurement Data
The Zehntner ZGM 1130 offers direct access to measurement data in csv-format without requiring software thanks to USB device functionality. This model also features single, multiple and even continuous scan gloss measurements and features easy to use multi-language menu guidance.
Proceq’s Zehntner ZGM 1120 is a portable precision glossmeter with the smallest dimensions for measurement. Able to handle all surfaces from matt to high gloss, the top-selling ZGM 1120 can take measurements on small, curved and very hard to reach surfaces.

For coatings, plastics and general materials
1120.6: ZGM 1120 Glossmeter 60°
1120.26: ZGM 1120 Glossmeter 20° and 60°
1120.268: ZGM 1120 Glossmeter 20°, 60° and 85°
For Foils and Paper
1120.2T7T: ZGM 1120 Glossmeter 20° Tappi and 75° Tappi
Transmit Data Directly to your Computer
The Zehntner ZGM 1120 opens the gateway to more efficient and productive quality control by the gloss measuring sensor transmitting the measuring data directly to the computer via USB-interface.
You will find the Zehntner ZGM 1120 useful for the various needs of production as well as the demanding requirements in the laboratory. This glossmeter is intelligent and user-friendly from the very beginning: starting at the calibration, continuing through the whole measuring procedure and concluding with data analysis.
The Zehntner ZOL 1150 Online-Glossmeter is a tailored gloss-measuring system for industrial areas for contactless online measurement of all gloss ranges from matt to high gloss up to 2'000GU.

The GX1 transforms the GS9000 into a high-resolution structural assessment system for concrete slabs, bridge decks and pavements. Its dense, dual-polarisation array captures detailed 3D data across wide areas, supporting reinforcement and cover mapping, moisture and deterioration assessment, and analysis of asphalt and pavement layers. Live visualisation helps confirm survey coverage on site, while post-processing tools produce clear, report-ready condition maps.
1. Define the inspection area
Import the structure, bridge, pavement or survey background.
2. Collect closely spaced profiles
Capture 35 longitudinal and 15 cross-polarised channels with dense spacing.
3. Review coverage in the field
Use live radargrams and time slices to confirm that the required area has been captured.
4. Process the dataset
Apply velocity, gain, background removal, migration, filtering and topographic correction as appropriate.
5. Generate diagnostic maps
Create depth slices, reinforcement maps, layer information or application-specific condition maps.
6. Integrate with the engineering assessment
Export figures, mapped anomalies and raw data for inclusion in the engineer’s final interpretation and report.
