Measurements International Resistance Bridges

Temperature

Measurements International is a manufacturer of a series of very low
temperature coefficient, precision, stable resistors to provide stability
and traceability for your temperature calibrations. MI has also become the
world’s leader in the supply of DC Comparator Technology Bridges for
Resistance Thermometry applications.

Model 6010T Automated Thermometry Bridge

> DCC Technology
> Current Reversal
> Front and Rear Panel Inputs
> Accuracy: <0.05 PPM
> Noise: <2nV
> IEEE488 and Manual Operation

The Model 6010T is designed for automated resistance thermometry
applications and provides the best accuracy and convenience based on
the most recent developments in current comparator technology.
The Model 6010T is completely self-calibrated directly against two
stable standard resistors of equal value for ratios of up to 1:1, and
against national standards for ratios ≤ 13:1.

Model 6015T Automated Primary Thermometry Bridge

> DCC Technology
> Current Reversal
> Front and Rear Panel Inputs
> Accuracy: <0.02 PPM
> Noise: <2nV
> IEEE488 and Manual Operation

The Model 6015T is designed for automated resistance thermometry
applications and provides the best accuracy and convenience based on
the most recent developments incurrent comparator technology.
The Model 6015T is completely self-calibrated directly against two
stable standard resistors of equal value, where only the short-term
drift of the resistors is important.

Model 6242T
Automated Secondary Temperature Bridge

> 0.01 to 10,000 Ohm Range
> Accuracy: 0.2 PPM (0.05m°C)
> Maximum Ratio: 14:1
> DC Current
> Comparator Technology
> Resolution: 0.01 PPM
> Linearity: 0.01 PPM

The Model 6242T is a high accuracy resistance bridge designed
specifically for resistance thermometry. Based on the Direct
Current Comparator, its unique DC Reversal eliminates thermal EMF
effects to provide you with fast, reliable measurements under a wide
range of real operating conditions. Four terminal measurements allow
you to make measurements up to 100 meters and more from the PRT.
The differential capability allows the resistance of one PRT to be
measured against another directly and provides the most accurate
comparison calibration technique.

Model 6242A
Automated SecondaryResistance Bridge

> 0.1 to 100M Ohm Range
> Accuracy to < 0.2 PPM
> Maximum Ratio: 1.3:1
> DC Current Comparator Technology

The Model 6242A Automated Secondary Resistance Bridge is
ideal for those laboratoriesinvolved in resistance and
temperature measurements that do not require the accuracy level of a
national laboratory. It is also designed as an automated, direct
replacement for the ESI 242-resistance measurement system.

The 6242A is based on the same Direct Current Comparator
technology found in the bridge used by major laboratories to maintain
their primary standards, the Model 6010B. Therefore, it has some of the
same features that metrologists have come to expect in an MIL bridge,
such as four terminal measurements over the complete range, automatic
current reversal to eliminate thermal EMF’s and a built-in self-calibration
routine.
