Keithley 2182A Nanovoltmeter 7.5 Digits Dual Channel Low Noise NanoVolt Meter

• The two-channel Model 2182A Nanovoltmeter is optimised for making stable, low noise voltage measurements and for characterising low resistance materials and devices reliably and repeatedly. It provides higher measurement speed and significantly better noise performance than alternative low voltage measurement solutions. The Model 2182A represents the next step forward in Keithley nano voltmeter technology, replacing the original Model 2182 and offering enhanced capabilities including pulse capability, lower measurement noise, faster current reversals, and a simplified delta mode for making resistance measurements in combination with a reversing current source.

• ·7-1/2 Digits
• ·1 nV resolution on 10.000000 mV range
• ·Make low noise measurements at high speeds, typically just 15nV
• ·p-p noise at 1s response time, 40 to 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
• ·Thermocouple linearization (8 T/C types) and cold junction compensation
• ·GPIB and RS-232 Interface
