Auto-Ranging Picoammeter Integrates or Reads Peaks

EG & G has developed an auto-ranging picoammeter that responds to full-scale current ranges from 1 nA (±3%) and 10nA (±2%) to 10µA (±1%) and provides a digital readout of either the peak input or the average input over a predetermined integrating period. The device was designed for thermoluminescent dosimetry (TLD), and provides a direct digital readout, in physical units, of average or peak dosage for full-scale ranges from 19.99 milliroentgens to 199.9R. Read full article
