Check the listing for details. Dosimeter Charger Model 909. Condition: Used. Listed at 150.00 USD. Features• 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, preventing spurious upscale fiber movement• LED Reading light to allow for easy charging/viewing• Residual static charge removed for improved accuracyThe charger’s 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 909B Dosimeter 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.The patented “kick” feature found on the 909B Dosimeter Charger automatically has the ability to remove all residual-static charge from dosimeters properly for improved accuracy. This prevents spurious upscale fiber movement.SpecificationsWeight: 10.6 oz (302 g)Size: 4" L x 4" W x 3.5" H (10.2 x 10.2 x 8.9 cm)Case: ABS PlasticControls: One turn potentiometerReading: Spring-loaded push rodPower: 1.5V “AA” BatteriesCharging Voltage: 40 V to 220 VOperating Temperature: 0° to 120°F (-18° to 49°C)Lamp: LED CHP Consultants dba CHP Surplus est. 2002 chpconsultants.com We offer 30-day return policy on our inventory.
