Digital nanovoltmeter 2182 series

portableAC

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. It offers a simplified delta mode for making resistance measurements in combination with a reversing current source, such as the Model 6220 or 6221. 1nV sensitivity Typically just 15nVp-p noise at 1s response time, 40-50nV p-p noise at 60ms Dual channels Measurement cycle is synchronized to the power line AC cyde Built-in thermocouple linearization and cold junction compensation Internai polarity reversai measurement technique Optimized for use vvith Model 6220/6221 current sources Delta mode current reversai measurement technique when combined with the 6220 or 6221 2182A/6221 combination synchronizes signal puises and measurements Benefits Provides accurate, ultra-low voltage measurements. Ensures low noise levels over a wide range of useful response times. Supports measuring voltage, température, or the ratio of an unknovvn résistance to a reference resistor. Minimizes variations due to readings that begin at different phases of the line cycle. The resuit is exceptionally high immunity to line interférence with little or no shielding and filtering required. Simplifies making accurate température measurements. Eliminâtes thermal error sources.
