Quantum Metrology
Even the best wire-wound resistors maintained in the most stable of conditions drift with time and temperature and can exhibit inexplicable changes in value. With the introduction of the MI model 6800 QUANTΩ (QHR) as the representation of the ohm, previously unattainable levels of repeatability and stability can now be achieved to < 0.02 ppm.
Temperature Metrology
MI manufacturers a series of automated bridges for resistance thermometry applications in addition to a family of very low temperature coefficient, precision resistors that provide the stability and direct traceability that is required for temperature calibrations at primary or secondary levels.
DC Metrology
Resistance...product line includes standard air and oil filled resistors, automated resistance bridges, range extenders, resistor baths and shunts.
Current...scanners, range extenders and shunts.
Voltage...10 and 100V reference standards, automated potentiometer and divider.
With over 20 years of experience, MI is the leading supplier of DC Resistance Measurement Systems and DC Standards around the world. Our broad product line covers resistance measurements from 1u to 100T ohms, and voltage measurements from a few micro volts to 1200 volts DC.
AC Metrology
Voltage...precision high voltage dividers.
Current...high quality and accuracy products include low and high voltage compensated current transformers and transconductance amplifiers.
Power...products range from power calibration systems to power analyzers.
Tan Delta & PF...automated high accuracy capacitance bridge for dissipation factor testing.
Loss Measurement...MI offers the most advanced system in the world today for measurement of transformer losses.
Capacitors...a complete line of standard reference capacitors for high voltage applications.
The measurement of electrical power and energy at high voltages and low power factors is becoming increasingly important as a way to reduce costs in an ever-growing industrial economy. A more precise means for scaling these voltages and currents down to usable levels is required. MI R&D teams are dedicated to providing the products to meet these demands.
