Used KEITHLEY 486 #293603492 for sale

KEITHLEY 486 electrometer is a versatile instrument for measuring small electrical signals with high accuracy. It is a true voltmeter, capable of measuring DC, AC, and pulse signals from a few microvolts to several volts with a resolution of up to 1 μV. It features a broad range of measurement ranges and a choice of DC, AC, and pulse measurement modes. The large dual-channel display lets you simultaneously read voltage, current, or other signals and information. 486 is designed to be used in a variety of scientific, industrial and service testing applications, such asresearch laboratories, semiconductor testing, biomedical and electrochemical measurements, chemical analyzers, machine controls, and semiconductor process control. It is also used in industrial process monitoring and control, data acquisition and display, electrical testing, and electronics production. Its wide dynamic range allows precise measurements over a relatively broad range of input signals. KEITHLEY 486 features a 10-turn high-resolution vernier-type adjustment knob for precise adjustment of the vertical magnitude with ranges from 0.005 μV to 34V in four-decade ranges. The precise amplitude level is indicated by the display's decimal point position. 486 includes both isolated and isolated guard inputs, which offer protection for sensitive measurements against electrical static charges, circulating currents, and leakage voltages. The isolated circuit ensures that signals from a probe tip indicated on the display are not affected by connected grounds. In addition, the vernier-type adjustment knob extends the full-scale dynamic range to 140V. KEITHLEY 486 also features transient filtering to reduce noise components and improve signal accuracy. The circuitry limits response time to 6.0 µs, so that continuous voltage measurements can be made with accuracy. In addition, 486 has auto-zero and self-calibration capabilities and an internal thermal protection circuit. The internal computer can move the sense leads off the calibration lines and execute auto-zero, thereby eliminating the need to manually set the zeroing point. The shielding of the amplifier circuitry in both channels prevents unwanted coupling or radiation of the sense leads. KEITHLEY 486 is designed to be driven by industry-standard 486-type peripheral interfaces and is warranted for one year. A variety of options and accessories are available for KEITHLEY 486. These include a wide range of adapters, 486 Electrochemical Station, and KEITHLEY 486 Noise Test and Calibration Kit.
