Data retrofit
Scale Link
Turns a display-only scale into a logged data source.
The challenge
Weights on a scale's display are written down by hand, or not at all.
Scale Link
Many weighing machines only have a display, so readings never reach a record unless someone copies them. Scale Link taps into the scale itself, reads the weight and sends it over Wi-Fi, so weigh-ins can be logged automatically.

Where it works
Animal weighing
Weights logged as animals are weighed.
Feed & stock records
Feed and store weights straight into records.
Kitchens & stores
Diet-kitchen weights captured as they happen.
What it does
Reads the display
Decodes the scale's multiplexed 7-segment display signals.
Or the load-cell chip
One wire on the scale's ADC data line gives the raw reading.
Wi-Fi out
Sends the weight over Wi-Fi.
Uses the scale's power
Runs from the scale itself or USB.
Minimal soldering
Taps onto the scale's board or display.
How it works
Fit
Open the scale and tap Scale Link onto its display lines or ADC.
Read
It decodes the weight as the scale measures.
Log
Weights travel over Wi-Fi into your records.
Why teams choose it
No hand copying
Weights go straight into records.
Keep your scales
Upgrade the machines you already own.
Live weights
See readings as they happen.
Better records
Fewer copying mistakes.
