Valid MeasurementsTM
Welcome to the home of the Anderson Loop and the Ultraguard on the web!

This web site is about fundamental new measurement circuit topologies from NASA and Valid Measurements. These measurement circuit approaches can outperform classic Wheatstone bridge and Kelvin circuits.

You can also learn here about the Ultraguard, the general case of guarding that even protects regions containing currents and voltage gradients.

We suggest you start by exploring the frequently asked questions about these new technologies. 


Thanks for looking up the Anderson loop, the Ultraguard and Valid Measurements on the web!
