The LB 200 is a very simple scintillation measuring system for the assessment of gamma activity in foodstuffs, liquids and bulk goods in Bq/l. Its microprocessor electronics allows the non-professional user to directly determine the radioactivity of gamma emitting radionuclides in liquids and solid matter in an easy and reliable manner down to approx. 20 Becquerel per liter or per kilogram in 1 hour measuring time.
