Ptw electrometer
Webelectrometer, instrument designed to measure very small voltages and currents. The quadrant, Lindermann, Hoffman, and Wulf electrometers measure electrical potential between charged elements (e.g., plates or fine quartz fibres) within the housings of the electrometer. The sensitivity of these instruments is about 0.01 volt. A much more … WebThe Cuban National audit program in radiotherapy is based on systematic on-site visits to the radiotherapy services. During the visit not only the whole radiotherapy process is reviewed but also some pre-defined dosimetry test cases are measured. This is a valuable
