7330 Series
AC/DC Precision Oil Based Resistance Standards
Very High Stability Calibration Laboratory Oil Based Resistance Standards
GUILDLINE INSTRUMENTS 7330 SERIES of Oil Based
Resistance Standards are designed for high accuracy
resistance calibration in air or in oil (Fluid Baths).
Having developed the most advanced series of Fluid
Baths (see our model 5600 Series), Guildline has now
designed a new oil based AC/DC Resistance Standard to
allow customers to get the highest performance for oil
based standards whether in our new 5600 Series of Fluid
Baths or in your own oil bath.
If you examine the 7330, you will find only Metrology
Grade Components for the case, connections and build.
Strategically placed case holes allow for maximum fluid
flow over the internal resistive elements, significantly
reducing the effects of temperature.
These resistance standards are suitable for both AC and
DC applications.
They are extremely useful as references for AC
Temperature Bridges, for the calibration of resistance
7330 SERIES FEATURES ranges of multi-function calibrators and high accuracy
Typical AC/DC Error <1.0 ppm at 1kHz
DVMs, as well as being used in more classical standards
and calibration resistance measurements.
Stability <2 ppm/Year
Temperature Coefficient < 0.2 ppm/
