Ludlum-Model 3001 General Purpose Digital Meters

The Model 3001 is a durable, lightweight instrument designed for alpha, beta, or gamma radiation survey. It can support up to four external detectors, each with its own set of calibration and user parameters. The instrument features a large, easy-to-read LCD screen and audible alarms and is controlled using a simple five-button interface. The unit body is made of high-impact plastic and splash resistant construction allows the instrument to be used outdoors. Three modes of operation are available – RATE, MAX, and COUNT – which can be selected by pressing the MODE button. Measurements can be collected in two sets of units (primary and secondary) for RATE and MAX modes in cps, cpm, Bq, dpm, mR/h, or µSv/h units. The user can switch between the two sets of units by pressing the UNITS button. The DETECTOR button is used to switch between the active detector settings, indicated by the colored LEDs above the control buttons. When enabled with the optional Lumic Data Logger Kit (PN: 4498-1019), data can be logged in any of the operational modes using the LOG button on the handle. Up to 1000 data points can be stored internally. Instrument setup can be done either through the front-panel controls or via the Lumic Calibration Kit (PN: 4498-1018). The Model 3001 is shipped ready to use with batteries and a calibration certificate.
