Features

Benefits

Current resolution as low as 1fA (6482)

Allows measuring ultra-low leakage currents in components, dark currents in optical devices, and beam currents in microscopy instrumentation.

Burden voltage as low as 200μV

Allows making current measurements with high accuracy, even in circuits with very low source voltages.

Dual-channel measurements (6482)

Simplifies analyzing multi-channel devices, monitoring currents in multiple locations on materials, and recording data from multiple sensors at once.

Choose from 0, 1, or 2 built-in voltage sources

Ensures you can find the voltage bias capabilities your application demands. Perform insulation resistance testing with the 500V source in the Model 6487 Picoammeter /Voltage Source.

Built-in analog outputs

Allows transmitting measurement results to devices like DMMs, data acquisition boards, oscilloscopes, or strip chart recorders for signal response and trend analysis.

Measure currents up to 20mA

Supports measuring currents high enough for applications such as measuring 4-20mA sensor loops.

Up to 1,000 readings per second

Offers the high throughput production testing demands.

Built-in Trigger Link interface

Simplifies synchronizing with other instruments and voltage sources by combining six independent selectable trigger lines on a single connector for simple, direct control over all instruments in a system.
