When the Wi-Fi drops, the monitoring shouldn't.

National Cold Vault builds a cellular temperature monitor for medical refrigerators. It runs on its own LTE-M connection and its own battery — so it keeps reporting when your network fails, your password changes, or the power goes out. Built for the inventory you paid for yourself: private-stock vaccines, GLP-1s, insulin, allergen extracts, compounded preparations.

It doesn't use your Wi-Fi

Wi-Fi loggers stop the moment the network drops, the router reboots, or someone changes the password. Ours has its own cellular connection and its own battery. A building outage doesn't take the monitoring down with it.

Records built for an inspection

Every reading writes to a tamper-evident log with device serial and timestamp. One click produces a PDF you can hand an inspector. Each probe is replaced annually with a new one carrying its own calibration certificate.

No IT involvement

No gateway, no network configuration, no IT ticket. Mount the magnetic backplate and run the probe through the door gasket — the radio stays outside the cabinet, where it can reach the tower.
