Pen dosimeter Arrow tech 138

RS_AR_US_4329-W138

The direct-reading dosimeter is a pocket carbon fiber electroscope with an ion chamber for detecting and indicating integrated exposure to gamma radiation and X-rays. It has a thin wall that allows penetration and radiation detection. This model comes with a hardened sapphire window that will not scratch, even in the most challenging conditions.

Dosimeters are extremely sensitive instruments. Although designed for rugged use, they must be handled with the same care as a wristwatch. Since dosimeters are factory-sealed, they cannot be repaired or adjusted in the field. Therefore, in case of instrument malfunction, it must be returned to the factory or your dealer. Dosimeters can be kept in working condition by simply cleaning the ocular lens and the charge switch insulator with clean water and a lint-free, grit-free cloth. Ensure that the charge switch insulator is absolutely free of lint and moisture at all times. Caution: Do not insert sharp objects into the charge switch housing and do not alter the parts. Irreparable damage may occur.
