Calibration records that keep your readings defensible
A gas analyser, a multifunction tester or a thermometer out of calibration invalidates every reading it produced. Gaffer records each instrument’s last calibration, next due date, the calibration body and the certificate reference — so your test results are traceable to a calibrated instrument.
Part of health & safety in Gaffer, which replaces a folder of last year’s templates with the dates changed.

The H&S paperwork gets done because it lives where the work is.
Risk assessments, method statements, permits, toolbox talks, inspections and registers, covering what an inspector, a main contractor or an insurer will ask for.
Win tenders that demand evidence, and sleep better knowing the file is complete.
Calibration records are one of the 40 things in health & safety. See the rest →
- Make, model and serial number for unambiguous identification
- Last calibrated date and next due date
- Calibration body that carried out the work
- Certificate reference for traceability
- Assigned user, so the instrument’s holder is known
- Next-due dates surfaced through the same expiry alerts as certificates
Step 04 of the job: on site
The engineer taps “On my way” and the customer gets a text with an arrival window. On site: clock in, photos, the certificate for the job — EICR, Gas Safety, whatever the trade needs — signed on the device. No signal? It syncs later.
Health & Safety is where calibration records sits, and that is the step it shows up in most. The rest of the job — quoting, scheduling, certificates, invoicing and payment — runs in the same system, on the same record. See the whole job →

Will this satisfy a main contractor asking for RAMS?
It produces the document they ask for, specific to the job rather than last year’s with the address changed, as a PDF you can send before you arrive. Their pre-qualification questions are their own, but the evidence is in one place.
Do the assessments have to be filled in on site?
That is the point of them, and the app is built for it — but they can be prepared in the office and signed on site, which is how most crews actually work.
Which plan is it on?
Every paid plan. Calibration records is included for unlimited users at no extra cost — the monthly, annual and lifetime plans differ only in how you pay.
