LB 147 / LB 148 Personal Contamination Monitor

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 measuring data
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)

Different versions

LB 147

The LB 147 has a removable hand probe for clothing measurements
Innovative scintillation technology for radiation protection
Robust design
Removable hand probe for clothing measurement
No counting gas required
Simultaneous separate measurement of α and β-γ radiation

1 2

LB 148

Simultaneous back-of-hand measurement with automatically tracked back-of-hand probe for optimum measurement geometry
Self-adjusting back of hand detectors
Time efficient measurement
Dual password hierarchy
Simple operation with graphic display and touch panel

LB 147 & LB 148 Alpha Sense

High efficiency and thus extremely low detection limits for alpha radiation
Specially designed protection grids
LB 147 Alpha Sense also available as Slim version
