Special Features:

Mftr. Classification: shielded grid; envelope material: glass; may emit harmful x-rays if operated at voltage in excess of 15.0kv must be shielded; differs from ml-lpt45 in the tube reading characteristic

Properties:

An inclosure, including two or more electrodes, in which a flow of electrons may occur through a vacuum or a contained gas. The electronic conduction takes place either by means of electrons emitted from a cathode or by ionization of the contained gas. Includes phototubes (photoemissive type only), geiger-mueller tubes, traveling wave tubes, cathode ray tubes and microwave tubes (klystron, magnetron, or the like). Excludes items whose primary purpose is to produce light energy. Also excludes photoelectric cell; and semiconductor device (as modified).
