The Model 19 MicroR survey meter is useful for low level gamma survey at that microR level. It is a compact, rugged, internal scintillation detector survey meter. The Model 19 Micro R survey meter includes an internal 1 in. x1 in. NaI detector, five ranges and splash proof shields for outdoor use. No external detector is required. Sensitivity, based on Cs-137 gamma, is typically 175 cpm/microR/hr. This meter over-responds to scatter and low energy gamma which makes it more sensitive than any survey meter available. The meter is ideal for finding gamma radiation leaks in lead shielding, radiation spills and geological fault lines. Range selections include 0 - 25, 0 - 50, 0 - 250, 0 - 500, 0 - 5000 micro R/hr.
- Built-In 1" X 1" NaI(Tl) Gamma Scintillator
- 5 Ranges
- Splashproof Shields
- Total Range from 0 - 5,000 µR/hr
