The Ludlum Model 43-135-1 is a large-area, 2π proportional detector designed for calibrating large-area alpha and beta sources. The windowless detector and source tray are sealed together via heavy duty clamps, which permit operating at higher pressures (up to 0.2 MPa).Request a quote Download Spec Sheet
