2182A Nanovoltmeter, Keithley Instruments (CAT#: STEM-LE-0110-LC)

The dual-channel 2182A Nanovoltmeter is improved for stable low-noise voltage measurements, and reliably and repeatably characterizes low-resistance materials and devices. Compared with alternative low-voltage measurement solutions, it provides higher measurement speed and much better noise performance.

Dimensions (WxDxH): 238 x 370 x 104 mm
Channels: 2
Interface: GPIB, RS-232C, SCPI
Noise Performance: 15 nV p-p at 1s (40-50 nV p-p at 60 ms)
Range: 10 mV to 100 V (and 100 mV to 10 V)

Maintain 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 can use a reversible current source up to 24Hz with 30nV p-p noise (typical) to coordinate measurements for a single reading. Average multiple readings to further reduce noise
Synchronization to line to provide 110dB NMRR and minimize the effect of AC common mode current
Dual channels support measurement of voltage, temperature or ratio of unknown resistance to reference resistance
Built-in thermocouple linearization and cold junction compensation
