Model AT-909
Features
- Capable of Recharging Dosimeters Thousands of Times
- Battery Powered
- Lightweight
- LED Reading Light
- One-Turn Potentiometer Control
The Model AT-909 is a compact, lightweight instrument designed to charge direct reading pocket dosimeters. See dosimeter Models AT-138 and AT-138S.
There is no need to remove the dosimeter from the charger for reading, thereby eliminating the gravitational-induced effect from changing the orientation of the dosimeter. This design is spring-loaded, with a positive mechanical stop, making it nearly impossible to damage dosimeters through use of excessive charging force. A one-turn potentiometer functions as the control. All residual charge is removed from the dosimeters to ensure accurate readings.

Headphone Jack
This modification for survey meters adds a headphone jack to the instrument body so headphones can be used to monitor click-per-event audio and audio alarms. Headphones are helpful when the instrument is being used in areas with high ambient noise levels or in areas where the audio would be distracting to others, such as in a medical or office environment.
Shoulder Strap
This 1.8 m (6 ft) adjustable shoulder strap is a great way to keep your hands free while operating survey meters. The nylon strap with a wide rubber comfort pad can also be helpful for conveying some of the heavier instrument/detector combinations in the field.
