Chain of Custody Tracking for Instruments and Compliance Equipment
Know where every instrument is, who has it, and who is responsible — at all times.
Lost Instruments, Missing Records, and Unclear Responsibility
Many companies track calibration dates but do not track chain of custody.
When an instrument is overdue, missing, or under investigation, companies often struggle to answer basic questions:
Without chain of custody tracking, these questions are difficult to answer during audits and investigations.
Where is the instrument?
Who has it?
Who was responsible for it?
Was it in service while out of calibration?
Was it sent in for repair or calibration?
When was it removed from service?
Complete Instrument Chain of Custody
Every custody transfer creates a record showing who, what, when, where, and why — so you can always reconstruct exactly where an instrument has been.
Cambri tracks:
- Who the instrument is assigned to
- Who currently has custody
- Instrument location (truck, lab, warehouse, manufacturer, etc.)
- When custody changed
- Why custody changed
- Instrument status (in service, in lab, in transit, out of service, quarantined)
- Full history of transfers
Defensible in Any Audit
When an auditor asks where an instrument was during a specific date range, Cambri can produce a timestamped custody history showing every location, every transfer, and every responsible party.
Real-Time Visibility
Managers and supervisors can see the status and location of every instrument at any time — not just during audits. No more calling around to find out where a gas detector is.
Prevents False Overdue Reports
When an instrument is sent to the lab or manufacturer, Cambri updates the status so it is not flagged as "in service overdue." This eliminates false positives in compliance dashboards.
See How Chain of Custody Works in Practice
A gas detector fails calibration in the field. Here is exactly what Cambri records — step by step — from failure to return to service.
Calibration Fails in the Field
Technician performs calibration check. Gas detector fails. Instrument is immediately flagged.
Removed From Service
Instrument status updated: Out of Service. Department supervisor notified. Instrument is no longer counted as active.
Transferred to Calibration Lab
Technician → Calibration Lab. Transfer recorded with timestamp, reason, and signature.
Lab Sends to Manufacturer
Lab determines repair is needed. Calibration Lab → Manufacturer. Transfer recorded. Status updated: At Manufacturer.
Repaired and Returned
Instrument is repaired, re-calibrated, and returned. Manufacturer → Lab → Technician. Full custody trail preserved.
Returned to Service
Instrument status updated: In Service. New calibration certificate attached. No gap in audit trail.
The Result
The instrument is not counted as "in service overdue" during its repair. When an auditor asks where this instrument was between March 3rd and April 12th, Cambri produces a complete custody trail in seconds — preventing confusion, false overdue reports, and audit findings.
Chain of Custody Features
Every feature is designed to answer one question in an audit or investigation: where was this instrument, who had it, and why?
Part of the Full Cambri Compliance Platform
Chain of custody tracking is built directly into the Cambri platform — it is not a separate module or add-on. Custody records are linked to calibration records, inspection records, and responsibility tracking automatically.
Always Know Where Your Instruments Are
Cambri provides full visibility and documentation for instrument custody, location, and responsibility — so you are always ready to answer auditors, investigators, and management.
