Model 909B Dosimeter Charger
The Model 909B Charger LED Reading Light reduces re-zeroing time and effort by eliminating the need to remove the dosimeter from the Charger for reading. Simply view the scale while the dosimeter is resting lightly on the charger contact after re-zeroing. Reading in the same orientation as charging also minimizes the effect that gravitational induced fiber movement has on dosimeter accuracy and precision. The Model 909B Charger charging contact is spring-loaded and has a positive mechanical stop. This design feature makes it virtually impossible to damage dosimeters through excessive charging force.
- Capable of charging any Direct-Reading Dosimeter
- Conforms to ANSI N42.6-1980
- Operates on two 1.5 V “AA” Batteries
- Has the ability to “Kick” or remove all residual charge from dosimeters properly, which prevents spurious upscale fiber movement
- LED Reading Light to allow for easy charging/viewing
- Residual static charge removed for improved accuracy
Charging Voltage: 40V to 220V

Direct-Reading Dosimeter with Sapphire Window
Model W725 Order (4349)
The Direct-Reading Dosimeter is pocket-size, carbon-fiber electroscope with an ion chamber for detecting and indication of integrated exposure to Gamma and X-Ray radiation. It has a thin wall which permits the penetration and detection of radiation. This model comes with a hardened sapphire window that won't scratch even in the toughest of conditions.
Dosimeters are extremely sensitive instruments. Although they are constructed for rugged use, they should receive the same care as a wristwatch. Since dosimeters are hermetically sealed at the factory, they cannot be repaired or adjusted in the field. Therefore, if instrument malfunctioning is experienced, the instrument should be returned to the factory or your dealer. Dosimeters may be maintained in operating condition simply by cleaning the eyepiece lens and the charging switch insulator with clean water and a cloth that is free of lint and grit. Make sure the charging switch insulator is absolutely free of lint and moisture at all times. Caution: Do not insert any sharp objects into, or tamper with parts in the charging switch recess. Irreparable damage may be done.
Arrow-Tech, Inc. recommends a yearly calibration of the Direct-Reading Dosimeter which is generally consistent with good health physics practices. More frequent calibration may be necessary should the user's license require a shorter calibration interval.
