Hitachi-Aloka Compact survey meter 

  PDR-303 is a well-designed Gamma survey meter for ambient dose rate measurement with a comfortably compact shape. Semiconductor detector with the reasonable water proof (splash proof) structure enables comfortable measurement for any user. TFT color LCD assists users to read the value, and sufficient alarm features (display and sound) inform users when the dose rate exceeds the preset level.

The PDR-303 has a wide measurement range and a large-sized color LCD in its compact body, which makes it possible to show you the measured data in the display selectable from various modes such as Digital & Analog, and to output data to a USB port of a PC simply.
