The Floor Monitor LB 165/166 is a mobile measurement device with large-area proportional counter tubes.
The Floor Monitor LB 165/166 is a mobile measurement device with large-area proportional counter tubes for the detection of surface contamination caused by radioactive nuclides.
The Floor Monitor is comprised of
- a trolley with three wheels
- a detector: Xenon detector or P10 flow-through counter tube
- a battery or rechargeable battery operated evaluation unit for acquisition (UMo II LB 134 or UMo LB 123)
The Floor Monitor is available in two versions: The LB 165 monitor operates with the permanently filled Xenon counter tube LB 6376 and measures Β- and Γ-emitters.
The LB 166 monitor operates with a flow-through counter tube LB 6386 and measures Α- and Β-emitters. The required continuous counting gas supply (P10 gas bottle with double pressure reducer) is accommodated on the trolley. The P10 gas bottle can easily be exchanged by the user.
