Exradin A4 Ion Chamber

92715 A4

Exradin A4 Ion Chamber

UNCOMPROMISING QUALITY

Ideal for calibration standards laboratories, health physics, research applications, manufacturing, and accelerator room scatter measurements

SHONKA-WYCKOFF SPHERICAL CHAMBERS ARE RELIED UPON BY STANDARDS LABORATORIES THROUGHOUT THE WORLD

Exradin Shonka-Wyckoff Spherical Chambers are designed for the precise measurement of radiation exposure and exposure rates. They are easily centered for precise positioning and are excellent for in air measurements.

FAST, PRECISE MEASUREMENTS

The design assures there are no stem or voltage soakage effects, providing precise and reliable measurements.

DURABLE CONSTRUCTION, BUILT TO LAST

The Spherical Chambers are constructed of durable C552 Shonka air-equivalent plastic, providing excellent conductivity and years of reliable use.
