Keithley Series 6400 Picoammeters
The cost-effective 5½-digit Model 6485 Picoammeter can measure currents from 10fA to 20mA, at speeds up to 1000 readings per second. The Model 6487 Picoammeter/Voltage provides higher accuracy and faster rise times than the 6485, a 500V source, and a damping function for use with capacitive devices. The Model 6482 Dual-Channel Picoammeter/Voltage Source offers higher measurement resolution than the Model 6485 or Model 6487 and dual, independent 30V voltage bias sources.
Benefits & Features
- 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.
