Ludlum Measurements, Inc. (LMI) products

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 buttons. The stunning 256-color, bit-mapped display provides an optimized presentation of the data and is accompanied with icons informing the user of the active functions and instrument status. All logged data are written in csv format to a plugged-in, industry standard, USB thumb drive for convenient retrieval by a PC spreadsheet or database program. Alarms are manifested using color changes on the display and an audio output.
