Philips 4060 Electrometer Triode
| The 4060 is a
triode with a very low anode current. Some applications
were for the measurement of Hydrogenion concentration in
solutions, the measurement of X-ray intensities with an
ionisation chamber, or the measurement of small light
intensities (small photo electric currents). A datasheet can be found here: http://tubes.mkdw.net/sheets/101/4/4060.pdf However, the tube shown here is a special version, with the getter deposited in a cup, in order to further minimize the leakage current. Thanks to Don Black who helped to identify this vacuum tube. |
Height : 165 mm (6.50") - Diameter : 57 mm (2.25")
The getter has been vaporized inside a thin glass cup.
| The filament forms 3 V's arranged in a horizontal plane with a flat anode below it, supported from the filament foot, and a flat plate control electrode "Grid" arranged above the filament, supported on long glass insulators so that the leakage between the control electrode and the other electrodes is reduced to the lowest possible value. |
