Abstract
The use of several types of multigrid tubes as electrometers has been investigated. They are shown to possess a number of advantages. Details are given for the 6BE6 and 7A8. Grid currents of between 10−13 and 10−14 amp. are obtainable with mutual conductances of the order of 5 microamp./volt and an amplification factor of 300.Keywords
