QMSYS GUM Professional

QMSYS GUM Professional, developed by Qualisyst Ltd., is a premier software in the Education category, falling specifically under Science Tools. The latest version, 4.9, offers a powerful and reliable solution for analyzing the measurement uncertainty of physical measurements, chemical analyses, and calibrations. It supports Windows XP, 7, and 8, with a file size of 18.1 MB, and its executables are named QGUM4.exe, and QGUMPro4.exe. Earlier versions, such as 4.5, also provide robust features for users.

This software is suitable for all types of calibration and testing laboratories, government institutions, and universities. It utilizes three powerful methods: the GUM uncertainty framework for linear and non-linear models and the Monte-Carlo method. With QMSYS GUM Professional, users can ensure compliance with all official standards, regulations, and guidelines, making it a highly trustworthy tool.

Notably, this program can explore complex scenarios like non-normally distributed input quantities and correlated input quantities with finite degrees of freedom. This capability is significant for those who need to model and validate uncertainties beyond typical cases described in the GUM and its supplements.

Highlighted features include:

• Suitable for both linear and non-linear models
• Supports symmetrical and asymmetrical distributions of the output quantities
• Expert analysis to determine appropriate methods for uncertainty calculations
• Regression analysis for expanded uncertainty equations
• Automatic fitting of probability distributions and coverage factor calculation
• Validation of GUF method results using the Monte-Carlo method
• Unlimited input and output quantities
• Various distribution models including Normal, Lognormal, and many more
• Histogram plotting and statistical evaluation
