The Ludlum Model 9DP, Pressurized ion chamber meter, provides highly sensitive measurements of exposure and exposure rate. It can simultaneously display the exposure rate and integrated value or the highest rate seen by the instrument. The integrated value can be reset (if desired) using one of the four convenient front‐panel mounted buttons.
