Overview

Particle size distribution
from your phone.

Granumetrics turns calibrated phone photos of coarse aggregate into a reviewable particle-size distribution. Capture the sample on site, inspect the detected boundaries and continue with the same analysis on the web.

Workflow

Capture, review
and report.

One analysis moves from phone capture to the reviewed result and report.

01Capture
New Analysis screen in the Granumetrics phone app

Capture the sample.

Name the sample, select the material and add calibrated photos. You can start offline and upload later.

02Review
Segmentation evidence review in the Granumetrics phone app

Review the detected particles.

Compare each source photo with its detected boundaries, then complete the review.

03Report
Particle-size distribution result in the Granumetrics phone app

Report or export the result.

Open the D-values and curve, then create a report or export. Sample name and Analysis ID stay unchanged.

Pilot

What you do
Capture one sample

Choose a representative sample and photograph it with the selected calibration method.

What we review
Check the complete result

We review capture, calibration, detected boundaries, D-values and the report with your team.

Pilot process

Run your first
analysis.

Try the complete workflow using your own aggregate and your own phone.
