Eisco Labs Resistance Substitution Board
This resistor board is extremely useful for all circuit applications. Great for electronics classrooms or labs, or for use in circuits under design or in testing conditions.
Comprised of 12 different resistors situated on a board, with standard preferred values from 33 ohms to 10M ohms in step ratio of 1:3. Select the resistance via the rotary switch and connect into a circuit by the 4 mm sockets terminals.
Board dimensions are 5 x 3.5 x 2 inches.
