Лічильник Гейгера

Лічильник Гейгера
Versatile, easy-to-use and compact precision instrument for measuring? -,? - and? -Radiation. With filter selection switch at the front of the Geiger-Muller counter tube for filtering out types of radiation (? -? And? -?,? And? Radiation), large display and integrated RS232 interface. Includes interface cable, Windows software and operating instructions.



The following functions and operating modes are available for measurement:

• Standard mode for displaying the current radiation level. Display of the equivalent dose as a numerical value and as bar chart and display of the time until a selected cumulative dose limit is reached (default 5? Sv / h). Also equipped with variable acoustic and optical warning threshold signal and display of average radiation from previous day.


• Pulse counting either permanent or with variable gate time. Gate time adjustable in seconds, minute or hours. Additional optional acoustic count indication.


• Count rate measurement. The pulses registered are measured successively and converted into a count rate (number of pulses per second).


• Integrated display of date and time for correct recording of measured radiation.


• The number of pulses registered is stored in the internal memory. This facilitates recording e.g. of weekly values ​​for up to 10 years.


• Computer docking station. The software enables the measured data to be evaluated and processed on an MS-Windows PC. Supported operating systems WIN 98 / SE, NT 4.0, 2000, XP.
