Exradin A1 Ion Chamber

92705 A1

Exradin A1SL Ion Chamber

UNCOMPROMISING QUALITY

For relative dosimetry scanning and measuring points in water, air, or other phantom material

A PERFECT BALANCE BETWEEN FAST SCANNING AND POINT DOSE MEASUREMENTS

The Exradin Miniature Shonka Thimble Chamber provides a perfect balance between fast scanning and point dose measurements within 1 cm in water, air, or other phantom material. The Model A1SL Thimble Chamber is the Slim-Line version of Model A1. It has the exact same internal dimensions and collecting volume as the Model A1, yet the entire chamber has the uniform diameter of 6.4 mm (0.250"), which is ideal when using a small phantom.

FAST, PRECISE MEASUREMENTS

The chamber features exceptional spatial resolution for relative dosimetry scanning and is capable of measuring small field sizes of 6 mm by 8 mm for accurate point dose measurements. Its waterproof construction 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

The Model A1SL is constructed of rugged C552 Shonka air-equivalent plastic, providing excellent conductivity and years of reliable use.
