Kelvio covers the whole HACCP paperwork with a single data flow: what comes in from the probes and the deliveries feeds logs, labels and reports.
Every fridge, cold room, blast chiller and freezer has a code and a range. Readings come from the probes or the app; out of range triggers a deviation and a corrective action becomes mandatory.
Reg. EC 178/2002: one step back. Supplier, product, lot, date and expiry on every delivery, with an explicit prompt for the lot when the delivery note omits it.
Supplier date, opening date and preparation date are different things: Kelvio keeps them apart and calculates the use-by date from the secondary shelf life in your manual.
Daily, weekly and periodic tasks become a checklist signed by the operator, with a history of who did what and when.
Six guided steps, pre-filled with the data already in Kelvio, and your HACCP manual is ready: hazard analysis, CCPs, prerequisites and procedures. It is adopted with a signature, stays unchangeable and is versioned at every revision.
Photograph the delivery note or upload the PDF: the AI reads supplier, products, lots, expiry dates and delivery temperature and fills in the register for you. You check and confirm.
An assistant that answers only from a curated database of Italian penalties and legal references: no invented amounts, no improvised sources. If the answer isn't there, it says so.
Permits, floor plans, training certificates, calibrations, pest-control contracts and lab analyses: one archive that watches the expiry dates for you.
One button: the adopted manual and every valid attachment become a single PDF (or a tidy ZIP) with separator sheets. It stays on the phone, so it works even without signal in the cold room.
Whoever supports you gets their own practice workspace with read-only access to the venues they follow: temperatures, non-conformities and documents, manual validation, and no way to alter the logs.
THE HARDWARE
One device plugs into power and covers the whole premises. The others hang outside the refrigerators: only a steel probe on a cable goes inside, under the door seal.
ONE PER ROOM
Plugs into power. No Wi-Fi password needed.
4G serves two purposes: avoiding having to ask the customer for the Wi-Fi password, and continuing to log even when the venue's internet connection goes down.
TWO COLD POINTS EACH
Outside the fridge. Only the probe goes inside.
The display is used during inspections: the temperature is read on the wall, without opening anything or using a phone.
The signal goes through
A cold room is a steel box, and steel blocks radio signals. With the electronics outside, the signal does not have to pass through anything.
Measurement is instantaneous
A bare steel tip follows temperature changes in seconds. A device enclosed in a box takes dozens of minutes, and meanwhile the log records something different from what is actually happening.
Si può verificare
The probe slides out and is calibrated against a reference thermometer. A sensor sealed inside a casing, if it drifts, cannot be checked: it must be discarded.
Many sensors declare only a single value, measured around 25 °C, and degrade as temperatures drop below zero — precisely where you need accuracy. A class A PT100 does not: tolerance is defined across the entire range.
Class A PT100 tolerance according to IEC 60751: ±(0.15 + 0.002 × |t|) °C.
They apply to us too. Here are our answers.
Does the entire device go into the refrigerator, or just the probe?
Only the steel probe, on a 1.5 m cable. The electronics stay outside.
What is the accuracy at −20 °C? Not at room temperature: at −20.
±0.19 °C. And the complete table is above.
If the connection drops for six hours, are those six hours recovered with the timestamp when they were measured?
Yes. 10,000 readings in memory, each with the measurement timestamp, not the sending timestamp.
Can the probe be replaced, or is the device discarded?
It unplugs from the cable. It can be replaced in one minute and verified against a reference thermometer.
Technical illustrations, not to scale.
A record is only worth something if it cannot be rewritten afterwards. That is why the Kelvio archive is technically append-only.
Every reading is chained to the previous one with a digital fingerprint: editing or deleting a value would break the chain and be obvious during an audit.
Strict separation per business: no other customer, and no unauthorised consultant, can read your records.
Managed backups, access logging and full export at any time. The data stays yours.
The demo opens a venue that has already been lived in: two days of real readings, a non-conformity to close, lots about to expire, signed checklists, a full document archive with certificates and floor plans, and the HACCP manual generated from the data. No credit card, no account.
Enter the demoTwelve months of flawless values are less credible than a few deviations handled well. Kelvio does not hide deviations: it detects them and makes you document what you did — product assessment, technical intervention, verification of the return to range.
