Well Counter Type 43


The Type 43 Well Detectors are the most sensitive gamma counter designs available, providing high quality data and minimizing counting time.

   Product Detail


Well Counter Type 43
This detector is similar in construction to the scintillation probes types 41 and 42 as used in our portable contamination meters. The integral lead shield provides adequate shielding for RIA determinations so in conjunction with the Mini-Assay type 6-20 the combination becomes a transportable gamma counter. Disposable plastic liners are available for the well.
