Fluke 742A-1

Resistance Standard
The Fluke 742A-1 is one of our refurbished 1Ω Resistance Standards.

The Fluke 742A Series covers values from 1 ohm all the way to 10 megohm. These are the finest-quality air resistors you can buy. They’re durable, easy to maintain, and easy to use.

Their excellent temperature stability allows them to be used from 18°C to 28°C with typically less than 2 ppm degradation. Using the calibration table supplied with the standards, which lists corrections in 0.5°C increments, this uncertainty can be reduced to near zero.
