Euromechanics medical has developed and manufactured ion chambers for few customers since many years in large quantities and is well experienced in this field.

The chambers are designed after estabished recommendations to chamber volume and geometry and provide best accuracy and long term stability.

 

The chambers are calibrated at the Calibration Lab in Seibersdorf, Austria, BNT and TNC connectors are available.

 



The ionization chamber EPC400 is a waterproof therapy ionization chamber for absolute dosimetry in high-energy electron beams. The measuring volume of 0.4 cc and mechanical design is close to the recommendations by Dr. Roos. The entrance window is made of 1mm PMMA, the chamber volume is vented through the cable connector. EPC400 is delivered with a calibration certificate. EPC400 can be used also for depth dose curves in photon beams, and as well in particle beams.

The ionization chamber EPC300 is a waterproof therapy ionization chamber for absolute dosimetry in high-energy electron beams. The measuring volume of 0.046 cc and mechanical design is close to the recommendations by Prof. Markus. The entrance window is made of 1mm Shonka, which gives the chamber extra rigidity. The chamber volume is vented through the cable connector. EPC300 is delivered with a protection cap and calibration certificate.
