Keep instrument identity, calibration schedules and measurement evidence together. Calibration Management gives metrology and quality teams a shared record of what is due, what was measured, who reviewed the evidence and which restrictions remain open.
Calibration orders in one list
An independent Metrology Reviewer approves the proposed technical plan and interval.
Every feature works on the same records. Pick one to see the screen your team works in.
Identify each instrument, range, custodian and permitted use.

Maintains identity, tenant configuration and configured connectors without bypassing technical or quality decisions. Scope checks apply on the server to reads, writes, files and exports. A person cannot approve an item they prepared, performed or requested, even after a role change or when holding additional authority. Independent approver eligibility is evaluated against authenticated identity and immutable provenance. Quality Managers may prepare assessments but a different eligible Quality Manager must approve them. Emergency action can add a hold; no emergency role bypass releases an instrument.
Operational reports that retain measurement context and unresolved exceptions.

Identify the instrument fleet, locations, measurement ranges and responsible custodians. Technical owners supply approved methods, decision rules and uncertainty evidence.
Resolve duplicate identities and missing serials. Preserve historical status and distinguish missing evidence from an established passing result.
Assign preparation, technical review and quality release responsibilities. Test identity-based separation, tenant scope, file access and export authority through the API.
Schedule a real-shaped test case, retain as-found observations, submit a certificate and independently review it. Include a failure that triggers historical impact and a separate release request.

Click Get started, then use Proto to configure Calibration Management for your business. Bring the instrument register, approved methods, current certificates and named decision owners. Choose the first instrument group and configure the approval steps around the way your team works.
Follow an instrument from its approved method and due date through original measurements, certificate review and release history. When a result raises a concern, connect the investigation to earlier use records and the quality decisions that follow.
Certificate acceptance records the Metrology Reviewer's assessment of the evidence. A correctly reported failure can be accepted while the instrument remains held. Quality Manager release is a separate decision against the current evidence and every unresolved restriction.
Bring external laboratory certificates into the same review process as internal work. Keep the provider, service scope and original evidence together, with file or portal connections configured for your laboratory.
The coordinator proposes an interval with evidence, and the independent Metrology Reviewer approves it. There is no universal default claimed as a NIST requirement. Changes apply prospectively and retain previous obligations.
The instrument remains restricted and the quality team assesses potentially affected historical use. A later satisfactory result does not close that investigation by itself. Missing use history must receive explicit treatment.
Corrections append a linked record with a reason and preserve the original observation. Submitted evidence and accepted certificate files cannot be silently overwritten. A revised certificate may require dependent decisions to be reviewed again.
Your qualified reviewers select the applicable methods, assess measurement evidence and authorise release. Calibration Management keeps those decisions connected to their supporting records. Laboratory accreditation and regulatory obligations remain with your organisation and its service providers.
An assistant can prepare evidence for review. It cannot bypass the independent Quality Manager decision, make up missing evidence or use administrative access as approval authority.
The assessment identifies potentially affected use and records its disposition or escalation. Product withdrawal, customer notification and recall execution remain in the customer's authorized quality process. The calibration app tracks evidence and acknowledgements.
Start free, then use Proto to change fields, steps and approvals before your team goes live.
