MI 9210A, MI type 1 ohm standard<\/h3>\n

The MI 9210A MI-Type standard was developed by Measurements Instruments<\/a> after years of research by the NRCC and MI. This model is now offered as an improved resistance design to replace the L&N Thomas-Type One-Ohm standard, as well as other values.<\/p>\n

These improvements have been achieved through a new annealing process of the element and changes in structural assembly.<\/p>\n

Historical data now shows that the MI 9210A is the most stable oil-filled resistor commercially available. The 9210A model has a long term drift of less than 0.2 ppm per year and a temperature coefficient of less than 0.05 ppm \/ \u00b0C.<\/p>\n

In every country there is only one institute that uses these kinds of standards. In the other cases a set of precision resistors is used which cover the different decades.<\/p>\n
