Temperature calibration services for mission-critical instruments.
Orbital Metrology provides NIST-traceable temperature calibration services for the instruments that keep your processes in spec—dry block calibrators, RTDs, thermocouples, thermometers, infrared thermometers, temperature chambers, and data loggers. Based in Greater Seattle, we serve aerospace, medical device, pharmaceutical, and advanced electronics manufacturers who need calibrated equipment back in days, not weeks.
Understanding the process
What is temperature calibration?
Temperature calibration is the process of comparing a temperature-measuring instrument against a known reference standard and documenting the deviation at each measured point. The reference standard is traceable to the National Institute of Standards and Technology (NIST), which means every calibration result connects back to a recognized national measurement chain.
During calibration, the instrument under test is exposed to a series of stable temperature set-points. At each set-point, the reading is compared to the reference. The resulting certificate shows the measured value, the reference value, the error, and the expanded measurement uncertainty—all the data your quality system needs to demonstrate control.
For manufacturers in regulated industries, temperature calibration is not optional. It is the foundation of process validation, product quality, and audit readiness. An uncalibrated thermocouple in a sterilization autoclave or an IR thermometer on an SMT reflow line introduces risk that auditors and customers will find.
Calibration scope
Temperature instruments we calibrate.
From portable dry-block sources to multi-zone environmental chambers, Orbital calibrates the temperature equipment your production floor and lab depend on.
RTDs (Resistance Temperature Detectors)
Pt100, Pt1000, and custom-element RTDs from process lines, validation rigs, and metrology labs.
Thermocouples
Type K, J, T, E, N, S, R, and B thermocouples across industrial furnaces, autoclaves, and environmental chambers.
Thermometers
Digital, liquid-in-glass, and bimetallic thermometers used in lab, process, and facility environments.
Infrared Thermometers
Non-contact IR guns and pyrometers calibrated against blackbody references at measured set-points.
Temperature Chambers
Environmental and thermal cycling chambers mapped and calibrated across their operating range.
Data Loggers
Multi-channel temperature loggers from cold-chain, warehouse monitoring, and validation applications.
The Orbital difference
24–72 hour turnaround. Not 8–14 days.
The industry standard turnaround for temperature calibration ranges from eight to fourteen business days. Orbital targets 24 to 72 hours from receipt to ship. That difference matters when production is waiting on a blocked chamber, a validation thermocouple is overdue, or a medical device line cannot release product without current cal stickers.
24–72h target lane
Temperature instruments move to the front of the queue. Bench priority is confirmed before pickup so your team can plan around real dates.
NIST-traceable references
Every calibration references standards with an unbroken traceability chain to NIST. Uncertainty budgets are documented per calibration point.
Audit-ready certificates
Certificates include instrument identification, measured values, reference values, deviations, expanded uncertainty, environmental conditions, and traceability statements.
Standards and accreditation
NIST traceability and ISO 17025.
Every temperature calibration Orbital performs is traceable to NIST through an unbroken chain of comparisons. Our reference standards—SPRTs, standard thermocouples, and precision thermometers—are calibrated by NIST or by laboratories with demonstrated traceability to NIST primary standards. This chain is documented on every certificate we issue.
Orbital follows the requirements of ISO/IEC 17025, the international standard for calibration laboratory competence. Our quality management system, measurement procedures, uncertainty analysis, and documentation practices are built to meet 17025 requirements. For customers whose auditors or customers require an accredited certificate, our accreditation path is actively underway and we are transparent about current status at the time of every engagement.
What this means in practice: when you receive a calibration certificate from Orbital, you get a document that holds up to quality audits, regulatory inspections, and customer requirements. The data is real, the traceability is documented, and the uncertainty is calculated—not estimated.
Regulated industries
Why temperature calibration matters for compliance.
Medical device manufacturers, pharmaceutical companies, and regulated aerospace suppliers cannot ship product without documented evidence that their temperature instruments are calibrated. Regulatory frameworks and quality standards require it:
- FDA 21 CFR Part 211 and Part 820 equipment qualification requirements
- ISO 13485 quality management systems for medical device manufacturing
- USP <1058> guidelines for analytical instrument qualification
- AS9100 aerospace quality management temperature-sensitive processes
- Pharmaceutical cold-chain validation and thermal mapping
Orbital calibrates temperature instruments for teams subject to FDA inspections, AS9100 audits, and ISO 13485 surveillance. Certificates are formatted for direct inclusion in your quality records, and turnaround time is fast enough that overdue calibrations do not stall production.
