Highlights

General

  • High sensitivity and uniform response
  • Simple operation with graphic display and touch display
  • Voice output in different languages
  • Permanent data memory for 10,000 measurement data points
  • Removable hand probe for clothing measurements

SCINT Technology

  • Unique simultaneous and separate measurement of α and β-y radiation
  • The individual types of radiation can be distinguished by means of special evaluation and correlation circuits, and thus separated and measured at the same time
  • High sensitivity even at low energies
  • No counting gas required

Different Versions

  • Slim version (LB 147 Slim)
  • Enhanced alpha sensitivity (LB 147 Alpha Sense)
  • Simultaneous measurement of the front and back of the hand (LB 148)
