NE2620 Dose-Doserate Meter

  NE2620 Dose-Doserate Meter



Designed for routine day-to-day measurement, the NE2620 can be used with a wide selection of chambers, offering a high degree of flexibility for various measurement applications. Applications include measuring electron, x-ray, & gamma doses, electric charge or current, Co60 units, and other radiation sources.
   Product Detail


The NE2620 Dose-Doserate Meter offers high standards of measurement of dose, doserate, charge or current. It may be calibrated for use with a 0.6cm3 chamber. Alternatively, charge or current may be measured when connected to other chambers.

Features:

  • Timer
  • Range selector switch
  • Displays for chamber output & time
  • Dual polarity bias voltage with 4-step divider ratios

The NE2620 Dose-Doserate Meter is designed for routine day-to-day measurements using 0.6cc chambers. In addition, it may be used with a wide selection of chambers to measure charge or current over the operating range. It is ideal for measuring electron, x-ray and gamma ray doses to confirm the beam doses from linear accelerators, 60Co units and other radiation sources as a final check before treatment.

The low range / high range selector switch is used to extend the range of measurements by a factor of ten, maintaining linearity within +/-0.1% at a resolution of +/-0.005%.
