Secondary Standard Dosimeter
Radimage Healthcare Digital Electrometer is an indigenously developed Electrometer.
Designed for Radiotherapy measurements. Its operation is simple, using a single button to start/stop and reset the measurement.
The quantity measured is charge, with a built‐in precision digital timer which helps to measure the signal current also. It has a wide measurement range extending from pico coulomb to micro coulomb thus making it useful for pinpoint dosimetry chambers, Farmer
chamber and Well type chamber for LDR & HDR Brachytherapy work. It has built‐in High
voltage supply directly applied to ionization Chamber, which can be set as ± V and ± V/2 for the evaluation of k saturation . Being indigenous and use of modular design makes the servicing and maintenance fast and economical.
