UNIDOS®
UNIDOS®
UNIDOS® is well known and accepted worldwide as the therapy dosemeter of choice with the best performance available on the market. Thousands of international users enjoy the high quality, the reliability and the excellent adaptation of this unique dosemeter. UNIDOS® as a reference class and secondary standard dosemeter is calibrated at the PTW calibration laboratory.

Ion chambers and solid-state detectors can be connected to the UNIDOS®. A comprehensive chamber library makes it possible to store calibration data of up to 30 chambers. Air density corrections are done by keying in air pressure and temperature, or by means of radioactive check devices. The check device data are stored in a database. An internal clock calculates the decay of the isotope radioactivity. UNIDOS® displays the measured values of dose and dose rate in Gy, Sv, R, Gy/min, Sv/h, R/min or Gym. The electrical values of charge and current are displayed in C or A. The device includes automatic leakage compensation, an auto-matic built-in system test and an RS232 interface. It features both mains and battery operation.
