Calibration service planning
On-site versus laboratory calibration
About 7 minutesLast reviewed: 2026-08-31
The appropriate arrangement depends on instrument type, transport risk, downtime, environment and accredited scope. Convenience alone should not determine the choice.
When to consider on-site calibration
Process-mounted, large or difficult-to-move instruments, and equipment that should be assessed in its installed condition, may suit on-site calibration.
- Reduces removal and process downtime
- Evaluates equipment in its operating location
- Requires suitable workspace, safety, power and environment
- The item, range and location must be checked against the scope
Advantages of laboratory calibration
Laboratory work suits methods requiring tighter temperature, humidity, vibration or setup control and access to specialized reference equipment.
- More consistent environmental control
- Supports complex references and setups
- Reduces site workspace and safety constraints
- Transport risk and equipment downtime still need planning
FAQ
Is every on-site service accredited?
No. The current scope must be checked for the instrument, range, method and service location before confirmation.
Is on-site calibration less accurate?
Not necessarily. Performance depends on the method, references, environment, setup and uncertainty evaluated for the specific work.
