Keithley 2182 Nanovoltmeter 

The Model 2182 is a 71⁄2-digit high-performance digital nanovoltmeter. It has two input channels to measure voltage and temperature.

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 Digits
• ·1 nV resolution on 10.000000 mV range
• ·Make low noise measurements at high speeds, typically just 15nV
• ·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
• ·Thermocouple linearization (8 T/C types) and cold junction compensation
• ·GPIB and RS-232 Interface
