ISO/IEC 17025 Compliant

Stop Using Excel for Uncertainty Budgets.

Are your uncertainty calculations trapped in massive, fragile spreadsheets? Calibrify's Uncertainty Engine handles Type A, Type B, distributions, and sensitivity coefficients automatically—fully compliant with ISO/IEC 17025.

A Smarter Way to Calculate

Built for metrologists, by metrologists.

Built-in Distributions

Select Normal, Rectangular, U-Shaped, or Triangular distributions with a click.

Automated Type A

We calculate standard deviation and degrees of freedom from your repeatability data automatically.

Monte Carlo Simulation

Run Monte Carlo simulations (MCM) for complex non-linear models to validate your GUM calculations.

CMC Verification

Automatically flag if your calculated uncertainty is better than your accredited CMC.

How It Works

1

Define Contributors

Add sources of uncertainty (Reference Standard, DUT Resolution, Environment, Drift, etc.).

2

Assign Distributions

Choose the probability distribution divisor (e.g., √3 for Rectangular).

3

Calculate Sensitivity

Enter sensitivity coefficients manually or let the system derive them.

4

Expand It

The engine combines standard uncertainties and applies the coverage factor (k=2) for 95% confidence.
