Ludlum Model 9DP Pressurized Ion Chamber Merlin Gerin or pancake style probeThe Ludlum Model 9DP is a digital, hand held pressurized ion chamber that provides highly sensitive exposure measurements of gamma and x ray radiation at energies above 25 keV and beta radiation at energies above 1 MeV. Measurements and instrument status are displayed on a large, 232K color, backlit LCD screen. The screen displays the current exposure rate as well as simultaneously displaying either the integrated exposure rate or the peak exposure
