Thermo ASP-2/HP190A Survey Meter

(Product Number ASP-2/HP190A)

The ASP-2/HP190A is a portable radiation survey meter designed to measure alpha and beta contamination as well as ambient gamma levels. An end-window GM Detector is utilized to supply excellent sensitivity. The Detector can easily be detached from the instrument, if desired, to probe areas too tight to accommodate the entire instrument or to more ergonomically position the meter for viewing while performing measurements.
