DOSE 1 Reference Grade Dosimeters for Radiation Therapy

Product introduction

DOSE1 is a portable, single-channel, high-precision reference-grade electrometer. Its measurement indicators clearly exceed the standards specified by IEC 60731 and AAPM. It has extremely high accuracy and provides excellent performance in a wide dynamic range. resolution ability. The electrometer can measure absorbed dose using ionization chambers, semiconductor probes, and diamond probes. The stability of the ionization chamber response can be verified and cross-calibrated using a radioactive check source.

Features

•Large, high-contrast, large viewing angle (160°) electronic luminescent display, which can completely display all measured values, ionization chamber parameters and correction factors.

• Ergonomically designed operation interface, intuitive and easy-to-use soft keyboard, pop-up menu.

• Multiple measurement results can be displayed simultaneously: dose, dose rate, average dose rate, charge, current and dose per MU.

• In order to verify whether the working status of the equipment itself, connecting cables and ionization chamber is normal, as a standard configuration, the equipment has electrical inspection source, leakage current and bias voltage test functions.

• Can store up to 40 different detectors and the same number of correction factors as 10 radiometric sources.
