Digital Thermometer Calibration Toolkit (ISO 17025) — Procedure + Uncertainty Budget Excel — CPGL-CAL-002

Complete Digital Thermometer Calibration Toolkit for ISO/IEC 17025 Laboratories

Save weeks of development time with this ready-to-use calibration toolkit designed for accredited and aspiring-accredited laboratories. Fully aligned with ISO/IEC 17025:2017 and ISO GUM (JCGM 100:2008).

This bundle includes:

1. Calibration Procedure (Word .docx) — CPGL-CAL-002

• Covers ice point, particular point, and full-scale calibration methods
• 10 uncertainty sources with sensitivity coefficients (ci)
• Welch-Satterthwaite formula for effective degrees of freedom
• Student-t coverage factor lookup (not assumed k=2)
• Ready for your lab logo and document control

2. Uncertainty Budget Excel Template (.xlsx)

• Multi-point calibration worksheet with formula-driven calculations
• YES/NO applicability toggles for each uncertainty source
• Built-in quality checks (combined uncertainty validation, k-factor bounds)
• Assumptions and Guidelines reference tab
• Student-t VLOOKUP table (1-30 degrees of freedom)
• 10 expanded uncertainty sources per calibration point
• Print-ready A4 layout

Uncertainty sources covered:

• Repeatability, resolution, reference standard, drift, environmental effects, hysteresis, interpolation error, self-heating, lead resistance, and display rounding

Who is this for?

• Calibration laboratories preparing for ISO 17025 accreditation
• Already-accredited labs upgrading their uncertainty budgets to full GUM compliance
• Calibration managers and technical signatories
• Quality managers building or auditing calibration systems

Why this toolkit?

• Developed by an ISO 17025 approved signatory with hands-on lab experience
• Saves 40-80 hours vs building from scratch
• Meets assessor expectations for uncertainty documentation
