Description
The Radiation Alert Ranger Detector offers maximum performance in a lightweight, rugged nuclear radiation detector for surveying at the facility or in the field. The Ranger has been designed for industrial environments, but it still has all of the features you’ve come to love in the lab. It’s small, handheld, digital NORM meter and offers excellent sensitivity to low levels of alpha, beta, gamma, and x-rays.
This model has built in efficiencies for common isotopes to calculate activity in Bq and DPM. It has a backlit digital display, a red count light, and a beeper that sounds with each count detected. Other features include selectable alert levels, an adjustable timer, and an optional wipe test plate for swipes. Internal memory and the free Observer USB Software allow you to download your data, and set computer alarms.
Each unit includes a carrying case, Xtreme boot, stand, Mini-USB cable, Observer USB software, certificate of conformance.
Specifications
| Detector | Internal Halogen-quenched, uncompensated GM tube with thin mica window, 1.4-2.0 mg/cm2 areal density |
