Product Overview

The two-channel Keithley 2182 Nanovoltmeter is optimized for making stable, low noise voltage measurements and for characterizing low resistance materials and devices reliably and repeatably. It provides higher measurement speed and significantly better noise performance than alternative low voltage measurement solutions.

Features and Specifications of the Keithley 2182 Nanovoltmeter include:

• Make low noise measurements at high speeds, typically just 15nV p-p noise at 1s response time, 40-50nV p-p noise at 60ms
• Delta mode coordinates measurements with a reversing current source at up to 8Hz with 30nV p-p noise (typical) for one reading. Averages multiple readings for greater noise reduction
• Synchronization to line provides 110dB NMRR and minimizes the effect of AC common-mode currents
• Dual channels support measuring voltage, temperature, or the ratio of an unknown resistance to a reference resistor
• Built-in thermocouple linearization and cold reference junction compensation
• Flexible, Effective Speed/Noise Trade-offs:
  • Easy to choose the best speed/filter combination for a particular application’s response time and noise level requirements
  • The ability to select from a wide range of response times allows optimizing speed/noise trade-offs
  • Low noise levels are assured over a wide range of useful response times, e.g.,
• Metrology Applications: 
  • Combines the accuracy of a digital multimeter with low noise at high speeds for high-precision metrology applications
  • Its low noise, high signal observation time, fast measurement rates, and 2ppm accuracy provide the most cost-effective meter available today for applications such as intercomparison of voltage standards and direct measurements of resistance standards
• Nanotechnology Applications:
  • Combined with the Model 622X current source or Series 2400 SourceMeter® instrument is a highly accurate and repeatable solution for measuring resistances on carbon nanotube based materials and silicon nanowires
• Research Applications:
  • Its 1nV sensitivity, thermoelectric EMF cancellation, direct display of “true” voltage, ability to perform calculations, and high measurement speed makes it ideal for determining the characteristics of materials
    such as metals, low resistance filled plastics, and high and low temperature superconductors
