New – ISOBudgets Simple Uncertainty Calculator for ISO 17025 – Version 6

The Best Uncertainty Calculator for Estimating Measurement Uncertainty

This is the most versatile uncertainty calculator for Microsoft Excel. You can use it to estimate uncertainty for anything as long as you need to follow the GUM method.

Personally, this is the uncertainty calculator that I use most.

Made For Every Lab

It can be used by:

• Calibration Labs,
• Testing Labs,
• Chemical Labs,
• Microbiology Labs,
• and more.

Includes Advanced Features

It is designed to work for all types of users, from beginner to professional. It is simple to use with a lot of automated features and includes advanced features experienced uncertainty estimators want, such as:

• Sensitivity Coefficients,
• Advanced Probability Distributions,
• Degrees of Freedom,
• Coverage Factor Options,
• CMC Uncertainty Calculator,
• and more.

If you need to estimate uncertainty, you will want this calculator.

Take a look at the information and images below to learn more about the Simple Uncertainty Calculator.

Add Up to 20 Sources of Uncertainty

Include up to 20 sources of uncertainty in your uncertainty budget. This is great so you can include every significant contributor in your uncertainty analysis.
 

Plus, this uncertainty calculator includes some amazing features:

• Sensitivity Coefficients,
• 9 Different Probability Distributions,
• Degrees of Freedom,
• Coverage Factor Options,
• CMC Uncertainty Calculator,
• and more.

Plenty of Room to Add Notes for Each Source of Uncertainty

Don’t forget how you quantified that uncertainty contributor? Document it in the notes section so you will never forget. This uncertainty calculator gives you plenty of room to write all of the notes you will ever need.
 

Select Your Preferred Coverage Factor

Pick the right coverage factor for you. With a simple dropdown menu, you can select whether you want to use “k=2” or the Student’s T-table.
 

 
Most people use the k=2 coverage factor when estimating uncertainty. However, some advanced users prefer to use the Student’s T table to calculate the coverage factor based on the effective degrees of freedom. This uncertainty calculator gives you the ability to select the option that you prefer with a simple dropdown menu.

Tons of Probability Distributions to Choose From

Whether you are a beginner or an advanced uncertainty estimator, this calculator has all the probability distributions you need to estimate uncertainty. There are 9 different types included.
 

Automatically Round Your Uncertainty to Two Significant Figures

Tired of rounding uncertainty to 2 significant figures? Now, it is automatically done for you. The Simple Uncertainty Calculator rounds each expanded uncertainty to 2 significant figures so you always report the right value.

Find Your Larger Uncertainty Contributors Fast

Want smaller uncertainties? Start focusing on reducing the largest contributors to uncertainty. The Simple Uncertainty Calculator makes it super easy using conditional formatting to show you which contributors to target first.

 
This is an awesome new feature. People ask me how to reduce their uncertainty (all of the time). This feature removes the guesswork and shows you exactly which uncertainty contributors will help you get smaller uncertainties.

Plus, it is a good feature for evaluating your uncertainty analyses. If you see a contributor that is significantly different compared to your other uncertainty budgets, you can take action to fix it before an assessor does.

Automatically Generate CMC Uncertainty Equations for Your Scope of Accreditation

Stop wasting time trying to figure out how to express a CMC Uncertainty equation in your scope of accreditation. Let the Simple Uncertainty Calculator do this for you. It will create 3 options for you so you can quickly decide and update your scope of accreditation.

Quickly Estimate Uncertainty for Your Measurement Range

Quickly estimate uncertainty for your entire measurement range. The Simple Uncertainty Calculator includes a verification table calculator that you can use to verify the results of your uncertainty analysis and estimate uncertainty at common test points you use during testing or calibration.
