Fluke 742A Resistance Standard Equivalency Guide

IET is pleased to offer a full line of equivalent resistors our SRL Series for those looking for the Fluke 742A Resistance Standards   
IET Labs has been manufacturing standard resistors since 1976.  Primary impedance standards: resistance, capacitance, and inductance are the core of our business.   
Our products have evolved from the engineering behind GenRad and esi (Electro Scientific Industries) the two most respected names in impedance
Where IET Labs is not as large as a company or has as a worldwide recognized name as Fluke but in the world of impedance we are much respected and almost every NMI and primary lab in the world has a number of our products. The Fluke 742A is a very good resistor, from a great company but you should be confident that making resistors is what IET Labs do best and I can promise you that the SRL series should surpass your expectations.

Unlike the Fluke 742A which is only available at a couple, of values, IET SRL Resistors are available from any value from 1 mΩ - 1 TΩ.  

You can see from the following chart, our SRL Resistors are equivalent or superior in every specification
