Keithley Series 6400 Picoammeters
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.
Keithley Series 6400 Picoammeters
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. |
