Product Manual
The compact GammaView is lightweight, easy to carry and operate detector with a 1x1 Nal scintillation detector that accurately measures gamma contamination and exposure. Perfect for use in the lab, facility, and in the field. Provides high levels of sensitivity to low energy Gamma and X-ray. The GammaView can also be used as a single-channel analyzer (SCA). This function allows a “window” to be set to focus on a specific energy region of the gamma spectrum, effectively reducing the background count.
The Observer USB Software reads in Total Counts, CPM,μR/hr, mR/hr, CPS, μSv/hr, and has the ability to collect, log the data received, set the calibration date and settings, and echo the readings collected on a PC. The data is displayed on a graph, as well as a digital on-screen meter. Data can be saved or printed in various ways, including a spreadsheet format. The dwell/count time can be adjusted for each point on the graph and the length of time for the count can be set . The software display has adjustable settings as well as a settable alarm.
