ZG Technology Co., Ltd. is a Chinese maker of metrology-grade 3D scanners; development and production are in Wuhan, and since 2021 it is part of Hexagon. The range covers handheld RigelScan, AtlaScan and CereScan scanners, HyperScan optical tracking, marker-free MarvelScan, PhotoShot photogrammetry and the MarvelProbe CMM.
The specifications come from the manufacturer's pages. Accuracy depends on the measuring conditions and is confirmed for a specific instrument; the manufacturer publishes no article numbers, spare parts catalogue, prices, lead times or warranty, and we do not declare EAEU, TR TS or Russian verification certificates. We are neither a dealer, nor a representation, nor an official supplier.
ZG Technology Co., Ltd. is a Chinese maker of metrology-grade 3D scanners founded in 2014 in Wuhan; address: BLDG #1, Dingxin Industrial Park, #18, Jiayuan Road, Hongshan District, Wuhan, China. It grew out of the photogrammetry centre of Wuhan University and joined Hexagon Manufacturing Intelligence in 2021. More than 50 patents and 2,000 projects are claimed.
Development and production in Wuhan
Handheld RigelScan scanners come in base, Plus and Elite versions. The blue laser handles shiny and dark surfaces, with HDR mode and a wireless option. RigelScan Plus: 2,100,000 measurements per second, 22 + 1 + 5 blue laser lines, 0.02 and 0.01 mm accuracy, 0.015 + 0.035 mm/m, 1 kg. Elite: 1,350,000 and 900,000 measurements per second with 14 + 1 + 5 lines.
Part size, material and accuracy
AtlaScan is a multi-mode metrology-grade scanner with 26 + 1 + 14 blue laser lines and resolution down to 0.01 mm. Hole accuracy is specified separately at 0.02 mm; volumetric accuracy is 0.015 + 0.03 mm/m, or 0.015 + 0.015 mm/m with PhotoShot. It weighs 1 kg; a portable CMM and Super Reference are optional.
For holes state the tolerance
RIGELSCAN Super uses 51 blue laser lines and delivers 3,380,000 measurements per second. Three working distances — 300–600, 600–1300 and 1300–2500 mm — cover small features and large structures. Accuracy up to 0.075 mm and volumetric accuracy of 0.1 + 0.015 mm/m are verified to VDI/VDE 2634 part 3 in an ISO 17025 laboratory. Laser class 2M, weight 1.3 kg.
State the maximum part size
CereScan is a compact handheld scanner weighing 0.65 kg: 2,480,000 measurements per second, 26 + 1 + 7 blue laser lines. CereScan SE weighs 0.54 kg and reaches 4,000,000 measurements per second with 34 + 1 + 17 lines over USB 3.0 and Wi-Fi 6. ZGScan 717 uses 14 + 1 red lines: 480,000 measurements per second, 0.03 mm accuracy, 0.83 kg.
For field work: weight and power
MarvelScan positions itself by built-in photogrammetry and needs neither a tracker nor applied markers. Volumetric accuracy: 0.05 + 0.02 mm/m without markers, 0.015 + 0.035 mm/m with markers, 0.015 + 0.015 mm/m with PhotoShot; the built-in photogrammetry averages 0.007 mm/m. Hole accuracy reaches 0.03 mm, depth of field 600–5,000 mm, and the CMM option gives 0.03 mm at 60 Hz.
For parts that cannot take markers
HyperScan works with the ZG-Track tracker, so the scanner moves freely over a large part with no markers. Super: 5,220,000 measurements per second, 34 + 1 + 7 blue laser lines, tracking up to 7.0 m and 100 m³, 0.02 mm probing accuracy, parts 0.1–12 m, 7.4 kg tracker. Ultra: up to 5.5 m and 50 m³, 0.03 mm probing.
State the object size and volume
PhotoShot Max is a wireless photogrammetry system: 0.015 mm/m volumetric accuracy at an average deviation of 0.005 mm/m, and 0.02 + 0.015 mm/m together with a ZG scanner. A 2,000 mAh battery with a replaceable pack runs three hours, communication is over Wi-Fi 5G 802.11ac, and the display shows status. Weight 900 g.
For large parts: the dimensions
MarvelProbe measures with a contact stylus and positions itself by reverse positioning — against a portable panel or pre-calibrated room — so parts are measured in sequence. Accuracy is 0.03 mm with 0.03 mm single-point repeatability; volumetric accuracy is 0.05 + 0.02 mm/m and 0.02 + 0.02 mm/m with scanner photogrammetry. Weight 500 g, ruby stylus 3.0 or 6.0 mm.
State the features to measure
AutoMetric and MarvelScan Galaxy are robotic inspection cells. AutoMetric combines a robot, a ZG scanner and a workstation; MarvelScan Galaxy adds a pre-calibrated bay. Power is AC 220 V, the range −20 to +40 °C, WLAN and USB include external IO. The software covers scanning, inspection and automation modules.
State the cycle and part range
GScan uses white light (LED) and captures surface colour together with geometry, mapping the texture to within a pixel. It reaches 550,000 measurements per second, a single scan takes under two seconds, accuracy is 0.05–0.1 mm and resolution 0.2–0.5 mm. Objects from 0.03 to 4.00 m are recommended; handheld, turntable and projection modes available.
For texture: material and size
RigelSLAM-S scans while moving and positions itself by SLAM without GPS, computing in real time. Range 0–120 m, 16 sensors, 320,000 measurements per second, a 360 × 270° field of view and 0–3 cm relative, 2–5 cm absolute accuracy. Battery 2.5–3 h, storage 500 GB, IP54, weight 1.6 kg, touch screen and RigelSee software.
State the area and accuracy
ZG scanners run the maker's software: ZGScan, HyperScan, GScan 3D Software, ArtMapping for registering 2D images with 3D data, and RigelSee for the mobile scanner. Export formats are .stl, .ply, .obj, .txt, .xyz and .asc, point clouds .asc, .txt and .csv, meshes .stl, .obj and .wrl. PolyWorks, Geomagic, CATIA V5, SolidWorks, NX and PC-DMIS read the data.
State your downstream software
Applications are grouped by industry: aerospace, automotive, heavy industry, moulds and castings, rail transport, wind energy, cultural heritage, medical, consumer goods and VR/AR. Typical tasks: dimensional inspection against CAD, reverse engineering, wear analysis, measurement of large weldments, sheet metal inspection and Hole Flash Capture.
Describe the industry and task
The replaceable layer: ZGFreeBox-II wireless modules (1.0 kg, 3,400 mAh), ZGFreeBox-II v2 (6,600 mAh, Wi-Fi 6E), ZGFreeBox-S and ZGFreeBox-T for optical tracking, 3.0 and 6.0 mm ruby styli with 30, 60 and 100 mm extensions, targets and scale bars, battery packs, USB 3.0 and Ethernet cables. Article numbers are not published.
State the instrument and part
The process is described as a pre-sales stage (RFI, initial talk, qualification, analysis, solution) followed by delivery and after-sales service: spare parts, repair, on-site support and training. The minimum order is one set, packed one set per suitcase, shipped by air express. Lead times, service prices, warranty and SLAs are not published.
A part, a repair or training
State the part size and material, the surface condition, the required accuracy and tolerance, the inspection volume, and the working conditions — workshop, field or laboratory. For tracker systems the maximum part size matters, for automation the cycle time, for photogrammetry the object size and volumetric accuracy.
The replaceable layer: ZGFreeBox-II and ZGFreeBox-S/T wireless modules, ruby styli of 3.0 and 6.0 mm with 30, 60 and 100 mm extensions, targets and scale bars, battery packs, USB 3.0 and Ethernet cables. The manufacturer lists spare parts service, repair, on-site support and training, but publishes no article numbers or spare parts catalogue.
State what is required: a scanner matched to the part, a replacement stylus or module, photogrammetry for a large object, automated in-line inspection, training or service. Add the material, dimensions and destination city. We will say what the documentation confirms and what needs separate checking.
