Description
The 8009 is a protected test device for measuring volume and surface resistance. It provides good electrostatic shielding and a high insulation resistance up to 1100 V. The 8009 is designed for safe operation with the 6517A or 6517B. Opening the cover of the 8009 switches off the 6517A or 6517B voltage source automatically. The 8009 is suitable for sheet metal samples with a diameter of 64 mm to 102 mm (2½ to 4 inches) and a thickness of up to 3.2 mm (1⁄8 inches). It ensures good sample contact with uniform pressure (from 6 to 10 lbs depending on thickness) on smooth parallel samples. With the switch on the front of the 8009, you can switch between volume and surface resistance, with the 6517A or 6517B configured to automatically calculate and display the corresponding result. The 8009 allows direct measurement of the specific pass resistance up to 1018 Ω-cm (on 0.1 cm thick samples) and the specific surface resistance up to 1017 Ω/square according to ASTM procedures.
