Price On RequestAutomatic Threshold Detection Automatically detect the start and stop of radiation exposure, allowing sequential measurements without resetting the electrometer. Low Noise, Repeatable Measurements Exceptional 0.001 pA to 500.00 nA range, 0.01 pC to 999,999 nC range. 0.1% repeatability and exceptionally low leakage of less than 1 fA. Digital filter eliminates nearly all the effects of noise, resulting in stable, exact measurements. Powerful Data Management MAX COMM software allows for comprehensive control of dose and dose-rate measurements, chamber detectors, remote operations and data logging.
