image

PDM-501 is an electronic pocket dosemeter with high sensitivity for Gamma (X-ray) in a pocketable shape.
The accumulated dose is easy to read with the digital display. This is one of the best suited models for personal exposure measurement.

Features

  • For measurement of personal exposure to Gamma
  • High sensitivity and wide range from 0.01 μSv to 1 Sv
  • Alarms by sound, flashes of light and vibration
  • Easy to read by digital indication of LCD
  • Measurable equivalent dose rate from 0.01 μSv/h to 10 mSv/h
  • Measured value is maintained even when the power is turned off*1
