2182A Nanovoltmeter

The two-channel Model 2182A Nanovoltmeter is optimized for making stable, low noise voltage measurements and for characterizing low resistance materials

  In our effort to bring our customers the highest level of precision measurement capabilities, Fluke Calibration is proud to offer these precision metrology grade products from Keithley Instruments. Renowned as a leader in low-level precision electrical measurements, these selected Keithley products present an opportunity to help you further reduce uncertainties in your lab. The two-channel Model 2182A 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.

  • 7 1/2 digit resolution provides 1 nV sensitivity on 10 mV setting
  • High accuracy: +/- (2 ppm rdg + 1 ppm rdg)
  • 3x lower noise than the Agilent 34420A at 1 PLC
  • Make low noise measurements at high speeds, typically just 15 nV p-p noise at 1s response time, 40-50 nV p-p noise at 60 ms
  • Delta mode coordinates measurements with a reversing current source at up to 24 Hz with 30 nV p-p noise (typical) for one reading. Averages multiple readings for greater noise reduction
  • Synchronization to line provides 110 dB 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 junction compensation
