Guildline Instruments 7334 Series of AC/DC Air Resistance Standards are designed for high accuracy resistance calibration in air, without the need for stabilization in a temperature controlled bath.
They can be used as AC or DC working standards, or as highly reliable and rugged transfer standards. They are extremely useful as references for AC Temperature Bridges, for the calibration of resistance ranges of multi-function calibrators and high accuracy DMMs, as well as being used in more classical calibration resistance measurements.
The 7334 series precision resistance standards are true AC/DC standards with essentially no AC/DC error up t01 khz, and are available in a wide range of ohmic values.
