A bench-grade densitometer for industrial radiography film, paired with a native calibration application built directly into the Avalon platform — no proprietary utility, no obsolete drivers, no serial-port roulette.
A purpose-built bench instrument: precision optics, USB-C, and a calibrated light path that holds its reading session after session. No moving parts the operator has to worry about, no consumables to keep on the shelf.
Stable light source, calibrated diffuser, and a fixed aperture — the same reading on the same sample, week after week.
Plug it in. Open the calibration app. Take a reading. There is no installer, no driver disc, no utility from a vendor that went out of business in 2009.
Small enough to live next to the densitometer it's replacing, heavy enough to stay where you put it.
Each unit ships with a signed calibration certificate. Re-calibration runs through the platform with a step wedge — start to finish in under five minutes.
The Avalon calibration app walks the operator through a step-wedge sweep, captures every reading directly into the platform's records, and prints a signed certificate the moment it's done. The reading goes straight to the equipment file — no transcription, no second app, no spreadsheet on the side.
