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. A powerful digital voltmeter, it provides higher measurement speed and significantly better noise performance for voltage meters than alternative low voltage measurement solutions.

● 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 24Hz 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 junction compensation
