This unit
The Fluke 742A-1 is a precision 1 Ω resistance standard engineered for high-accuracy calibration and verification in laboratory and field environments. This metrology-grade artifact delivers traceable, stable resistance values with no requirement for environmental controls such as oil or air baths, enabling on-site calibration work without infrastructure constraints.
Technical Specifications
