  • (1) Probe-Rite PS44D Series Prober
  • (1) Bausch & Lomb 7x Stereo Zoom Binocular Microscope Head without eyepieces.

This is not a fully operational probe station. The X stage has some ball bearings missing but can still be manually operated. The microscope head illuminator has some minor housing damage (see image.) An external vacuum pump is needed to operate this system. There is no power source for the microscope lamp module; lamp is installed but untested. Vertical heigh platform is operational.


Applied power to the probe and observed the green power lamp light. Connected a vacuum and pressure air source to the equipment and observed the operation of the various controls. Air pressure gauge is operational. The vacuum control puck mounted on the X stage does operate when the on and off buttons are pressed. Solenoid operation could be heard when the buttons were pressed. There is an "O" ring seal on the base of the lower platform that is not fully operational. This is due to the linear bearing strips that are missing and not providing a tight seal to the X translation stage. Internal components in the electro-mechanical section look good.
