Legal-trade metrology · Kenya
A weight no one can cheat.
Metriq builds legal-for-trade weighing scales and dispensers that use advanced technology to prevent cheating — so the number on the scale is one everyone can trust.
Why this matters
A wrong weight is a transfer of money.
Every weight is a price. When a scale reads light, a farmer hands over kilos they are never paid for; when it reads heavy, a buyer pays for product that was never delivered. Either way, money moves to the wrong side of the counter — quietly, one transaction at a time — until the people trading stop trusting the number between them, and the business built on that number starts to lose the suppliers and customers it depends on.
For most of the trade, the only assurance that a reading is honest has been a paper seal and a stamp from the day the scale was checked. But a seal only tells you the scale was right once, on the day an inspector signed it — it says nothing about what the scale is doing today, with a real load on it and real money changing hands. Metriq is built so the number can be trusted long after it leaves the workshop.
Built for legal-for-trade regulation
A digital version of the inspector's stamp.
Legal-for-trade weighing works the same way around the world: an inspector tests an instrument, applies a physical stamp, and a verification certificate follows. In Kenya that authority is the Weights and Measures Act (Cap. 513). Metriq is designed to fit that process and to make it harder to undo — the inspector's stamp becomes an electronic seal the instrument enforces itself, and the certificate becomes a tamper-evident record on the server.

Products
What we build.
Smart weighing scales
Bench and platform scales with enclosure-tamper detection. Open the case and the scale enters a tamper state — it stops showing readings until it is re-sealed and recalibrated with a fresh code.
More on scales →Automated dispensers
A separate line: measured dispensing that replaces weighing by hand. Set the quantity and the dispenser delivers it — farm chemicals, cereals and grain, kitchen ingredients — by volume for liquids, by weight for solids.

What happens when the seal is broken.
From a trusted reading to a locked one, the instant the seal is broken — the same on every Metriq instrument.
Coded calibration
The calibration switch is not enough.
On a Metriq instrument, flipping the calibration switch does nothing on its own. The device also needs a code — generated by the server, valid once, entered over Bluetooth from a phone. Use it and it is spent; the next calibration needs a new one.
It works the same way an STS token does on a prepaid meter. The authority to recalibrate stays with whoever holds the server — a regulator, or an operator like a tea factory running its own fleet — never with whoever happens to be standing at the scale.
Server → phone → scale. The code never lives on the device. Keeping it off the scale is what keeps the scale simple.
The aim
Where we want this to go.
For regulators
We want weights-and-measures authorities to adopt coded calibration as the standard — so every sealed instrument in the field is recalibrated only on the authority's terms.
For operators
An organisation running its own scales — a tea factory, a miller, a cooperative — holds its own server. The code still has to be entered before any calibration will take.
Tamper-evident by design
Enclosure-opening detection borrowed from electricity metering. A breached seal is recorded and readings stop until the instrument is made honest again.
Simple at the edge
Keeping codes and connectivity on the phone, not the scale, keeps the hardware cheap, rugged and easy to service.
