The UNIDOS E by PTW is a user-friendly, lightweight and compact  electrometer / dosemeter mainly used in routine dosimetry for radiation therapy. PTW ion chambers and solid-state detectors can be connected to the Unidos E Electrometer. A chamber library makes it possible to store calibration data. Air density corrections are performed by keying in air pressure and temperature. The UNIDOS E displays the measured values of dose and dose rate in Gy, R, Gy/min, R/min or Gy·m. The electrical values charge and current are measured in C and A. The large, high-contrast LC display is easy to read. The device includes automatic leakage compensation and an RS-232 interface. The high voltage between the ion chamber electrodes is checked automatically. UNIDOS E features both mains and battery operation.
