The fast dual channel electrometer TANDEM is suitable to perform field measurements referenced to an ionization chamber or accelerator monitor signal. The measured values can be used as a basis for absolute dose and dose rate measurements in radiation therapy.

In conjunction with the MP3/MP3-S Beam Analyzer, TANDEM is controlled by MEPHYSTO software for fast and accurate beam data acquisition. Using the TanSoft software, TANDEM can also be operated in standalone mode from a PC. TanSoft enables the user to operate the electrometer as a therapy dosemeter in accordance with IEC 60731, provides calibration and correction factors for various detectors and displays the measurement results.
