21 CFR 1.908. One PDF. Every load.

FSMA Sanitary Transport doesn't ask whether you tried to keep food safe — it asks whether you can prove it. iMatrix produces the temperature, door, and GPS log every auditor wants, on every reefer load, automatically. NEO-1 measures, Sentry-1 witnesses, FC-501 connects.

Continuous proof, not snapshot screenshots.

🌡

30-second cargo temperature

NEO-1 and the Neo-1P NIST probe report cargo-core temperature every 30 seconds. Below the trigger level, alerts fire to the dispatcher and the carrier's QA inbox.

🚪 Door-event timeline

Sentry-1 logs every open and close, including dwell time. An auditor can see whether the temperature drift correlates with a stop or a real failure.

One-click PDF export

Sensor readings, door events, GPS breadcrumbs, driver stops — formatted to the layout FSMA, PTI, and customer QA teams expect. Signed and time-stamped.

Three sensors. One regulator-ready record.

FSMA expects you to demonstrate temperature control across the load. That means more than a single probe — you need cargo-core, ambient, door state, and position. iMatrix gives you all four through three devices that share one cellular link.

From probe ping to FSMA PDF.

1 · Continuous capture

NEO-1 and Sentry-1 broadcast every 30 seconds. FC-501 aggregates, time-stamps with GPS, and uplinks. No reading is ever local-only — the cloud has it before the trailer crosses the next county line.

2 · Live alerting

Out-of-spec temp, door open at the wrong stop, sustained dwell — alerts go to the dispatcher's phone and the QA inbox the moment they trigger, with the GPS coordinates of the event.

3 · Per-load reconciliation

Cloud groups readings by trip. Pickup → drop-off forms a single FSMA load record with the relevant sensor data, door events, and GPS path attached.

4 · One-click PDF

Auditor calls? Pull the load. Click "FSMA Export." Signed PDF with every reading, every door event, every GPS ping. The format every FDA / state inspector expects.

21 CFR 1.908 and the rules around it.

FSMA Sanitary Transport — 21 CFR 1.908

Carriers must "design and maintain vehicles and transportation equipment to ensure they do not cause the food they transport to become unsafe." iMatrix retains every reading for the life of the vehicle and exports the documentation an inspector asks for.

Produce Traceability Initiative (PTI)

GTIN + lot + timestamp-correlated temperature records. When a recall comes in, you know exactly which load was affected and where it went — within minutes, not days.

HACCP / customer QA

Some receivers run their own HACCP plans on top of FSMA. iMatrix exports the same data in their preferred format — Sysco, US Foods, and Walmart all accepted.

Record retention

FSMA requires 12 months. iMatrix retains for the life of the device by default, configurable per fleet. Your data, your archive.
