Overview
The WPC-1150-GFW‑3.5 and WPC-1150-GFW-5 low background automatics are gas-flow proportional counters equipped with either a 3.5 in. (8.9 cm) or 5.0 in. (12.7 cm) detector configuration. Each counter incorporates a built-in color touch screen interface and is targeted toward Health Physics and environmental applications. They are ideal for large diameter air filters used in high-volume air samplers.
