Drawing ball validation tools that prove the draw was fair.
Auditors and regulators don't take your word for it — they read the report. The DBVS measures ball weight to 0.001g, auto-identifies RFID balls, and generates PDF reports you can publish to your regulator the same day.
A heavier ball is a less-random ball.
The difference between a random draw and a biased one is sometimes a few thousandths of a gram. A ball that's heavier than its set falls more often. A ball that's lighter floats. Weight-matched sets are the foundation of every certified lottery draw — and drawing ball validation tools like the DBVS are how you prove they stay matched.
Save time. Stay in compliance. Show your players the math.
Three tools. One audit-ready workflow.
DBVS — Drawing Ball Validation System
Standalone appliance. 0.001g scale. Auditor-ready PDFs.
A computer-controlled digital scale that weighs each ball to 0.001g accuracy. For RFID-equipped SmartBalls, the system auto-identifies each ball number and assigns the weight automatically — no manual lookup, no manual entry. Generates auditor-ready PDF reports tracking average weight, max/min, and long-term wear.

- Tracks average, max/min, and long-term wear across draw sets
Go/NoGo Gauge
Pass-through dimensional verification.
A simple, fast pass-through gauge for dimensional QC. If the ball passes through the larger aperture but not the smaller, it is within tolerance. The everyday tool for daily-spec checks and pre-draw verification.

Setra Industry-Standard Scale
The industry-standard ball scale.
Setra is the industry-standard weight scale used by lottery operators worldwide. We provide it pre-configured for lottery ball weighing and integrated with our reporting workflow — generate ball reports quickly and accurately.

Every reading. Every ball. Every audit.
The DBVS doesn't just measure — it logs, tracks, and reports. Every validation pass produces a timestamped PDF you can hand to your regulator, post on your transparency page, or archive for the audit cycle.
Average weight per set
The set-wide mean weight and standard deviation across every ball, batch-by-batch.
Max / min values
Highest and lowest weights flagged automatically — easy compliance verification.
Long-term wear tracking
Trend lines across months and years show wear-down and indicate when sets need retirement.
PDF auditor reports
Generates suitable-for-publication PDF reports — the same kind you publish to regulators and players.
RFID auto-assignment
For SmartBall sets, each ball weight is auto-tagged to its ball number — zero manual lookup.
Tamper-evident logs
Every reading is timestamped and logged for audit — a regulator can trace any reported value back to its original measurement.

What the tools look like.
The same shop that built your balls validates them.
End-to-end accountability
We manufacture the balls. We build the validation tools. We support both — fully accountable across the entire calibration chain.
Auditor-ready by default
Every report is built to a format regulators recognize. No re-formatting, no spreadsheets, no manual rework.
Workflow-integrated
DBVS, Go/NoGo gauge, and Setra scale plug into the same workflow — one operator can complete a full validation pass in minutes.
Standalone appliance
The DBVS is its own appliance — no external PC, no IT setup, no network access required. Plug in and validate.
