Exradin A14P Microchamber

Proven guard design yields stable, precise measurements and minimizes settling time by creating uniform field lines
Shell, collector, and guard are made of durable, long lasting Shonka conductive plastic
Use of homogeneous material throughout the chamber minimizes perturbation of the beam due to the presence of the chamber and optimizes measurements
Axially symmetric design of the chamber provides an uniform, isotropic response
Inherent waterproof construction eliminates need for additional protective coverings
Two separate stem pieces of 5.1 cm and 12.7 cm can be coupled together for ease of use
Cobalt-60 build-up caps of C552 and A150 are available
Ionization collection efficiency is 99.9% or better
Only for use in one polarity
Collecting volume is 0.002 cc

UNCOMPROMISING QUALITY

For superficial skin therapy measurements

FAST, PRECISE MEASUREMENTS

Its waterproof construction and two piece removable stem makes it ideal for use in water phantoms. The chamber vents through a flexible tube that surrounds the triaxial cable, ensuring the collecting volume is in pressure equilibrium with the surroundings. The design assures there are no stem or voltage soakage effects, providing precise and reliable measurements.

DURABLE CONSTRUCTION, BUILT TO LAST
