Keithley 487 Picoammeter/voltage Source Description:

  • Resistivity measurements (<1 Ohm to >10^16 Ohm)
  • +-500V source
  • 10fA sensitivity
  • 180 readings / second
  • GPIB

The Model 487 is designed for measurement of low currents and very high resistances. This instrument incorporates all the capabilities of the 486, and adds a programmable +/-500V source. This combination of picoammeter and voltage source provides a powerful high resistance meter and fast picoammeter in one instrument.

The 487 makes current measurements from 10fA to 2mA. Two voltage source ranges are available: a 500V range with 10mV resolution and a 50V range with 1mV resolution. A PRESET button allows the user to toggle between two separate source values.

The 487 sources up to 500V, measures the current with 10fA sensitivity, and then instantly calculates the resistance value, from 500mO to 5x10^16O. The unit displays either current or resistance. Reading intervals from 10ms to 1000s can be programmed, simplifying tests that require a predetermined soak time.

Two displays, one for current readings and one for voltage sourcing, permit the voltage setting and the measured current to be viewed throughout the measurement.

The Model 487 and the 6517A are the most effective test instruments for performing such tasks as resistivity, I-V measurements, component leakage, and insulation resistance. A common test procedure, written by the American Society of Testing and Materials, D257: D-C RESISTANCE OR CONDUCTANCE OF INSULATING MATERIALS, is easily performed with the 487 or the 6517A.

We offer the refurbished used Keithley 487 Picoammeter/voltage Source for sale and rental.

The Keithley 487 is fully tested and refurbished in our in-house ISO9001 calibration laboratory. We supply manuals, accessories, full warranty and a free-of-charge Certificate of Conformity. We can also provide the Keithley 487 with a fresh calibration for a small additional charge.

If you have under-utilised test equipment talk to us about trading-in or part-exchanging it towards the Keithley 487 or other refurbished test equipment.
