Radimage Digital Electrometer* RH-DEM 0517

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 ksaturation. Being indigenous and use of modular design makes the servicing and maintenance fast and economical..

Radimage Last Man Out Switch RH-LM0817

Advised by AERB “Last Man Out Switch” (LMOS) is designed for radiation safety. Soon after patient setup, the technician needs to press the LMOS after ensuring that nobody is present in the treatment room. This activates an audio‐visual alarm for 30 seconds and during this Wireless Last Man Out Switch period the operator needs to close the door and switch “ON” the beam. Works on latest micro controller based technology. Simple to install and easy to use.

*Can be supplied with ADCL USA calibration (optional) or BARC Calibration, date to be appointed by the user.
