Resistance Decade Box. Resistance Decades.
Direct reading - No fumbling with multiple slide or rotary
switches.
The family of digital substituters uses convenient side by side
thumbwheel switches. Simply dial in the desired values and use.
Accuracy over a wide range of ambient conditions is assured by
the use of resistors
with good temperature and power characteristics.
RS925D Decade Resistance Standard is a four-terminal,
continuously variable
resistance standard. Values from 10mΩ to 1.2MΩ can be achieved
using eight decade
switches.
Microprocessor-controlled and loaded with innovative features,
the ohmSOURCE
Resistance Box
HARS Series Resistance Resistor Decade is the best choice when
you need a
laboratory grade, tight tolerance, high performance resistance
decade box that is
also cost effective.
The HARS LX Series Resistance Decade Box represents the highest
accuracy version
of the resistance substituters for use in the most exacting
calibration and test
applications.
HRRS Resistance Decade is an economical, high performance, high
resistance
decade box for all laboratory, test, and calibration needs.
HPRS Resistor Decade. Economical, high performance, high power
resistance decade
for a variety of laboratory, test, and calibration needs.
A broad range of laboratory grade decade substituters for
applications requiring a cost
effective programmable impedance unit controlled manually and by
a computer.
In order to perform calibrations with a high degree of accuracy,
reference standards
must be employed at every range or decade of the measuring or
calibration
instrumentation.
The HATS-LR Series of transfer standards consist of 12 matched
resistors, of value R,
which may be connected in series or parallel combinations to
produce any number of
values such as R/10, R, and 10R, all with the same known
deviation, thereby allowing
progressive transfers to higher and lower decades.
The ZX74 Series of Decade Resistance Boxes are very high accuracy and stable six-dial instruments.
There are 4 versions in the series with a maximum resistance of 1,111,111Ω.
Switches are of the highest quality with low pressure contacts for long life and reliability.
