Radiation Dosimeter Geiger Counter DKS AT3509



Modern wide-range accurate microprocessor instruments to control personal dose equivalent Hp(10) and Hp(0.07) and dose rate of continuous and short-term x-ray and gamma radiation. Together with the reader connected to PC the dosimeter can be a part of automated monitoring system of staff dose burden. The dosimeters are intended to measure personal dose equivalent and dose equivalent rate x-ray and gamma radiation. They measure dose rate in a wide range and have separate audible and visual alarm.

Microprocessor processing and proper background detection ensure high accuracy of dose measurement within the wide dose rate measuring range. The microprocessor controls operation modes over, calculates, outputs data on a backlit LCD and performs self-testing.

- Compensative filter and electronic energy response correction by 4-channel analog processor
- Proof against the microphonic effect
- Self-testing mode
- Possibility to use separately or in a system



- Dosimeter
- Box
- Manual
