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.

A record per instrument, with the certificate reference that makes a reading traceable.
The calibration body and certificate reference are stored against the instrument, which is what turns a reading into evidence rather than a number.
Next-due dates join your certificate and qualification expiries in one alerting stream, so an instrument does not drift out of calibration mid-contract.
Make, model and serial number are recorded, so when a calibration certificate is questioned it is obvious which physical instrument it belongs to.
Calibration records sit with your equipment inspections, water hygiene logs and asset register in one platform.
Anything whose reading you rely on or certify from — gas analysers, multifunction testers, pressure gauges, thermometers used for legionella monitoring, torque wrenches. If a number from it appears on a certificate you issue, it needs to be traceable.
Usually annually, but it depends on the instrument, the manufacturer's guidance and the scheme you work under — some accreditation bodies specify intervals. Gaffer stores your next-due date rather than assuming one interval for everything.
Every reading taken since the last valid calibration is potentially suspect. That is why Gaffer stores the instrument's calibration reference against readings in the water hygiene logs — so the affected records can be identified rather than guessed at.
Yes. Records carry an assigned user, so an analyser that lives in one engineer's van is tracked to that person and its expiry reaches them.
