Secondary Standard Dosimeter




Keeping the tradition of providing excellent products for Dosimetry, QA and patient positioning for over three decades, Radimage Healthcare India Pvt. Ltd. (Meditronix Corporation) proudly announce indigenous manufacturing of complete range of Dosimetry products, including Electrometer, Ion Chambers, Well Chamber, Water Phantoms, Ion Chamber based Area Monitors, Last Man out Switch, extension cables etc. We undertake repairs for chambers and cables of any brand. The Dosimetry System is initially checked and calibrated at BARC, Mumbai.


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 saturation and economical.
