Keithley 2182

This Nanovoltmeter Low levels of DC drift and noise are among the best known attributes of DC nanovoltmeters.

In a typical nanovoltmeter, acceptable noise levels can be achieved by using extended integration periods of 30 seconds or more and by filtering the response.

When used in this way, Keithley’s new Nanovoltmeter has lower noise than either earlier types of nanovoltmeters or sensitive DMMs.

However, this design has been optimized to make low noise measurements in just a few seconds and to measure low resistance materials or devices by using the reversedcurrent method.
