Abstract
A current integrator employing a neon bulb has been used; it is found to require no correction of any kind, and to be independent of power supply fluctuations. The lowest current for which the integrator can be considered reliable is 0.05 microampere. Currents up to 30 microamperes have been integrated properly, and it is believed that currents up to 200 microamperes could be integrated by a similar circuit.Keywords
