Digital Thermometer Uncertainty Budget — ISO 17025 Excel Template — CPGL-CAL-002

Digital Thermometer Calibration Uncertainty Budget — Complete Excel Template (CPGL-CAL-002)

Ready-to-use ISO 17025 Excel workbook for digital thermometer calibration uncertainty analysis. Covers thermocouple, RTD, and thermistor-based digital thermometers across laboratory and industrial temperature ranges.

What You Get:

• Pre-built uncertainty budget with all Type A and Type B components for temperature measurement
• Automated Welch-Satterthwaite formula calculating effective degrees of freedom
• Built-in 30-entry Student-t lookup table for coverage factor (k) at 95.45% confidence
• Sensitivity coefficients (ci = ∂F/∂xi) auto-calculated for each uncertainty source
• YES/NO toggle switches to include or exclude individual uncertainty contributors
• Measurement results with auto-calculated expanded uncertainty and pass/fail assessment

Key Features:

• Compliant with ISO/IEC 17025:2017 and ISO GUM (JCGM 100:2008)
• Covers reference thermometer uncertainty, resolution, repeatability, stability, drift, immersion depth, and environmental factors
• Automatic unit conversion and sensitivity coefficient propagation
• Professional certificate-ready output with traceability documentation
• Works in Excel and Google Sheets — no macros required

Designed for: Calibration laboratories, quality managers, metrology technicians, and ISO 17025 accreditation bodies preparing for ILAC, A2LA, NABL, or UKAS assessments.

Pairs with: CPGL-CAL-002 Digital Thermometer Calibration Procedure (sold separately or as a bundle).
