Keithley 8009 Resistivity Test Fixture

Overview

The Keithley Model 8009 is a guarded test fixture designed for measuring volume and surface resistivity of solid materials. It provides excellent electrostatic shielding and maintains high insulation resistance up to 1100V for accurate measurements in accordance with ASTM standards. The 8009 is specifically designed for use with Keithley 6517A and 6517B electrometers, with an integrated interlock that automatically turns off the voltage source when the chamber lid is opened, providing safe operation.

Key Features

• Guarded electrode configuration eliminates edge effects in resistivity measurements
• Electrostatic shielding for accurate, noise-free measurements
• High insulation resistance rated to 1100V
• Accommodates sheet samples 64mm to 102mm (2.5 to 4 inches) in diameter and up to 3.2mm (0.125 inches) thick
• Uniform pressure application (6 to 10 lbs depending on sample thickness) for consistent contact
• Front panel switch to toggle between volume and surface resistivity modes
• Automatic safety interlock that de-energizes voltage when lid opens
• Enables measurement of volume resistivity up to 10^18 Ω-cm and surface resistivity up to 10^17 Ω/square

Applications

• Quality assurance testing of electrical insulating materials
• Material research and development for plastics, rubbers, and composites
• Certification and compliance testing to ASTM standards
• Industrial material characterization and acceptance testing
