Versatile, easy to use and compact precision instrument for measuring Alpha, Beta and Gamma radiation With filter selection switch at the front of the Geiger-Muller counter tube for filtering out types of radiation large display and integrated USB interface. Including USB cable, Windows software, and operating instructions. 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. 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. Radiation types: Alpha from 4 MeV, Beta from 0.2 MeV, Gamma from 0.02 MeV. LCD Display, 4 digit, numerical with display of measured variable, quasi analogue bar chart, operating mode indicators. Radiation detector: End window Geiger-Muller counter tube, stainless steel housing with neon-halogen filling. 38.1mm Measuring length. 9.1mm Measuring diameter. Mica window: 1.5 - 2mg/cubic centimeter. Gamma sensitivity: 114 pulses/min for 60Co radiation = 1 µSv/h in background radiation energy band. Background rate: 10 pulses per minute approx. Internal memory: 2 kilobytes. 3 years approximate Battery life. Dimensions: 163 by 72 by 30 cubic millimeter approximate.
