Miniature Probe

A wire probe 1 is carried by a hypodermic needle or similar tube 1a, mounted in a square section tube 2 secured in cantilever fashion in plastic block
3. An end of the probe is fixed in a brass block 4 by a screw 5 which also acts as the probe terminal.

Y direction motion is given by a screw 6, against which the block 4 is urged by a compression spring 7. Z direction motion is given by a screw 8 with a rounded end bearing on the upper surface of the unsupported part of tube 2. X direction motion is given by a screw 9 mounted in block 3 at an angle of 30 degrees and which terminates in a 60 degree cone. Screw 9 bears against a vertical side of tube 2.

The device is secured to a specimen table by a single screw, not shown, about which it is rotatable for coarse positioning.
