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 EIC400 is a Farmer type therapy ionization chamber for absolute dosimetry with measuring volume of 0.6 cc. The wall is made of graphite and the electrode of aluminium. The chamber volume is vented through the cable connector. EIC400 is delivered with a build-up cap and calibration certificate; available connector types are triaxial TNC or BNT.
