Refrigerated transport operates where temperature excursions aren't just spoiled product — they're customer rejections, insurance claims, and FDA audits. iMatrix puts the probe in the cargo core, the GPS on the tractor, and the FSMA record in the cloud. One timeline per load, exportable in one click.
NEO-1P NIST probe in the cargo core reporting every 30 seconds. Not "what was it at the dock" — what was it for the entire run.
Threshold breach → SMS + email to dispatch and driver within seconds. Escalation if no acknowledgment.
21 CFR 1.908 documentation built into every shipment record. Signed PDF per load, formatted the way auditors want.
Sentry-1 magnetic sensors log every open/close on reefer boxes. Correlated to GPS and cargo temp on one timeline.
GTIN + lot + timestamp-correlated temperature records. Recall scope in minutes, not days.
Big-box grocery QA teams demand NIST-traceable probes. We ship them with the certificate. That's the end of the conversation.
The full in-transit temperature monitoring stack with contextual NEO sensors + Micro Gateway.
Cold Chain →Continuous reefer-core monitoring with alerts before cargo spoils.
In-Transit Temperature →Sentry-1 door events + Neo-1P probe + FleetConnect GPS on one timeline.
Reefer Trailer Monitoring →21 CFR 1.908 Sanitary Transport documentation baked into cloud exports.
FSMA for Transport →Behavior scoring on perishable-cargo operations with insurance implications.
Driver Safety →ISO 17025-traceable probe in the cargo core. The defensible placement when QA asks.
BLE-to-cellular bridge in the tractor. Pushes reefer temperature on the same cellular link as FleetConnect GPS.
Tractor telematics with dual CAN bus. Correlates GPS + driver + engine data with cargo temperature.
Tell us fleet size, vehicle mix, and compliance context — we'll scope the hardware and pricing.
Talk to Fleet Sales →One tracker per truck or trailer, plus the sensors that ride in the load.
OBD-II FleetConnect gateway. GPS, cellular eSIM, and BLE aggregation for your Neo sensors.
Choose a plan →IP67, dual-CAN J1939 and BLE sensor bridging, with optional Starlink (FC-501-SAT) for routes that lose cellular.
Get a quote →Solar trackers mounted on the trailer — no powered tractor needed. The PRO scans your Neo sensors itself over BLE 5.4.

Cold storage that doesn't move — a warehouse, lab or pharmacy? Same Neo sensors, on a Micro Gateway instead of a truck.
