Information
The Keithley Model 181 is a highly sensitive nanovoltmeter
with a large, easy to read 5½ or 6½ digit display. The Model 181 is unique in that it combines microprocessor technology
with a new concept in low-noise, high-gain front ends,
resulting in a programmable instrument with sensitivity
down to 10nV. The Model 181 provides highly accurate,
stable, low-noise readings on seven ranges for DC voltage
measurements between 1OnV and 1OOOV. The mV ranges
use a special low-thermal input connector, while connections
for the higher voltage ranges are made through two
S-way binding posts. Additional versatility is afforded by
the inclusion of an IEEE-488 Interface which allows the unit
to communicate with other instrumentation.
