EM Electronics.

The EM Range of Low Level Voltage Measuring Instruments


The N11a has a very wide range of source resistance capability and has an equivalent noise resistance of less than 10 ohms. Sub-nanovolt resolution is possible. The N11a has many applications, including cryogenic measurements.


This is our latest and most advanced DC Nanovoltmeter. The N51 is even more suitable for cryogenic measurements and has been designed to measure sources at even lower temperature with the highest possible efficiency.
The new features of the N51 include an optically coupled output isolator and the ability to control range and filter settings remotely with the N51 remaining isolated.


The P13a is designed as a practical and easy to use picovoltmeter. Equivalent noise resistance less than 250 milli-ohms. Resolution down to 20 picovolts.
