Every completed service generates a digital, QR-signed hygiene certificate, not a generic "job done" note, but a specific, verifiable record of what actually happened during your clean. Here's what's on it and why each field is there.
What's on the certificate
| Field | What it verifies |
|---|---|
| Ozone reading (ppm) | The actual ozone concentration used during disinfection, not just "we used ozone," but the measured dose. |
| ATP reading | A biological cleanliness measurement, lower readings mean less microbial activity remaining on tested surfaces. |
| Date & location | When and where the service happened, ties the certificate to a specific, checkable job. |
| Before/after photos | Visual proof of the tank's condition, not just a written claim. |
| Crew ID & signature | A tamper-evident record of exactly who performed the service. |
| QR verification link | Scan it and it resolves to a live, verifiable record online, anyone can check it, not just the person who booked the job. |
Why this matters more than it might seem
A certificate that can't be checked is just a piece of paper. This one can, an RWA committee, a hospital compliance officer, a restaurant's FSSAI inspector, or a tenant can all scan the same QR code and see the same verified record. That's the difference between "we say we cleaned it" and "here's proof, check it yourself."
How long is it valid?
A certificate remains valid until your next scheduled cleaning or AMC renewal, it's a record of a specific service, not an ongoing guarantee, which is exactly why regular cleaning intervals matter.
