Femto Scientific provides ISO/IEC 17025 accredited thermometer calibration that keeps clinical and diagnostic laboratories CAP- and CLIA-ready — NIST-traceable certificates with as-found and as-left data and documented uncertainty for the thermometers, probes, and data loggers guarding your refrigerators, incubators, water baths, and vaccine cold-chain storage.
- Calibrated to ensure accuracy for survey
- NIST-traceable references to ITS-90
- As-found & as-left data on every certificate
- Documented measurement uncertainty (k=2)
- Survey- and inspection-ready documentation
- Onsite service for high-volume labs
- Cold-chain data logger & probe calibration
- Automatic recertification scheduling
Temperature calibration records your CAP inspector can check off without a second question.
Thermometer Calibration Requirements for CAP and CLIA Laboratories
Clinical laboratories accredited by the College of American Pathologists (CAP) or operating under CLIA must calibrate temperature-measuring equipment with NIST-traceable standards and keep the records available for survey. ISO/IEC 17025 accredited calibration is the cleanest way to demonstrate that competency for every refrigerator, incubator, water bath, and cold-storage monitor.
CAP Survey Readiness
CAP checklists require calibration records for temperature-measuring devices used in critical processes — refrigerators, incubators, and water baths. Our certificates document NIST-traceable calibration, the calibration date, as-found/as-left results, and reported uncertainty, exactly what surveyors expect.
CLIA 42 CFR 493.1252
CLIA requires instruments to be maintained and calibrated per manufacturer and quality-standard specifications, using NIST-traceable references within the established interval. Our accredited certificates meet those requirements and integrate with your LIMS.
Temperature-Critical Assays & Cold Chain
An out-of-tolerance thermometer can shift a temperature-critical assay or compromise vaccine and specimen storage. Accredited calibration with documented uncertainty and as-found data gives you the evidence to demonstrate temperature validity — and to scope any impact if an instrument is found out of tolerance.
A Full Calibration, Not Just an Ice-Point Check
A daily ice-point check confirms a single point; it is not a calibration. Accredited calibration characterizes performance across your use range with NIST-traceable references and documents it for CAP and CLIA compliance. Both belong in your quality program — serving different purposes.
- Multi-point calibration across the clinical range
- Digital thermometers, RTDs, thermocouples & probes
- As-found & as-left data with adjustment
- Documented expanded uncertainty (k=2)
- Barcode calibration stickers for asset tracking
- Electronic certificates for paperless QMS
Most CAP and CLIA laboratories calibrate temperature-measuring equipment at least annually. Compare service levels and turnaround on the thermometer calibration service page, or add continuous ARTEMIS remote temperature monitoring for your cold-chain storage.
CAP & CLIA Thermometer Calibration FAQs
Calibration frequency depends on regulatory requirements, instrument criticality, and usage intensity. Pharmaceutical laboratories under cGMP typically calibrate critical thermometers every 6 months or annually, with frequency justified in the instrument qualification documentation. Clinical laboratories under CAP or CLIA are required to calibrate temperature-measuring equipment at least annually. Research laboratories without regulatory mandates typically calibrate annually. High-criticality thermometers — those used in incubators, stability chambers, autoclave validation, or freeze-thaw studies — may require quarterly calibration. Femto Scientific can help you establish and document an appropriate calibration interval for your specific compliance program.
As-found data documents the thermometer’s measurement performance before any adjustment or correction during the calibration visit, providing a record of how the instrument was performing since the last calibration. As-left data documents performance after adjustment or correction, representing the condition in which the instrument was returned to service. Both data sets together provide before/after documentation required by GMP change control programs, CAP inspection checklists, and instrument qualification protocols. Femto Scientific’s Level 3 and Level 4 service levels include both as-found and as-left data.
All service levels include a calibration sticker with barcode applied to the instrument. Level 2 and above include an electronic calibration certificate documenting as-left measurement data at each calibrated temperature point. Level 3 and Level 4 additionally include as-found measurement data, documented expanded measurement uncertainty (k=2, 95% confidence), reference standard traceability information, environmental conditions during calibration, and the ISO/IEC 17025 accredited laboratory identifier. Certificates are delivered electronically in PDF format and are formatted for integration with quality management systems (QMS) and laboratory information management systems (LIMS).
NIST traceable thermometer calibration documents that the calibration results were obtained using measurement standards with an unbroken chain of comparisons to the National Institute of Standards and Technology (NIST) national temperature standards, based on the International Temperature Scale of 1990 (ITS-90). Femto Scientific uses NIST-traceable reference thermometers, calibrated temperature baths, and dry-block calibrators with current NIST-traceable certificates. This unbroken traceability chain is required by FDA, CAP, CLIA, and ISO compliance programs as evidence that your thermometers’ measurement results are metrologically valid.
Yes. Femto Scientific provides onsite thermometer calibration and repair across major U.S. laboratory markets including New York, New Jersey, Boston, Philadelphia, Baltimore, Connecticut, California, Texas, and many more cities. Onsite service is available at all service levels and is ideal for instruments that are difficult to ship, laboratory environments with large numbers of in-situ temperature probes, or facilities that require zero instrument downtime. Laboratories outside our direct service territory can use our secure, fast-turnaround mail-in thermometer calibration service with NIST traceable certificates delivered electronically.
