Seguro 160
A sealed, reusable NFC temperature logger built for regulated shipments.
Audit-ready temperature logging for shipments that require IEC 17025 traceable calibration certificates. Fast, accurate, tap-to-read temperature data — with the documentation to back it up.

Certified temperature logging, out of the box
NIST-traceable calibration included with every unit — no separate request, no added lead time.
Half a business card, 4mm thick
Fits into packaging that a USB logger never could — labs, kits, and last-mile parcels alike.
Tap-and-go NFC
No app required. Any smartphone reads the full temperature history in one tap.
Automatic delivery confirmation
The person who started the session is notified the moment it's read — no chasing status.

Questions People Actually Ask
Does the Seguro 160 include a calibration certificate?
Yes — standard with every unit. Each Seguro 160 ships with a digitally signed, NIST-traceable calibration certificate, downloadable and linked to its serial number.
Is the 160 more accurate than the 150?
The sensor is exactly the same one used across the Seguro line. What the 160 adds isn't a different sensor — it's the certified paper trail. For regulated and audit-ready shipments, that certificate is the requirement.
Do I need an app to read it?
No. Tap it with any NFC-enabled smartphone and the temperature history opens instantly in your browser.
Can I switch to the 150 later if my requirements change?
Yes. Both tags work on the same Seguro platform, so switching doesn't mean switching workflows.
