Multi-Detector Survey Meter - Model 3001
CE Seal

The Ludlum Model 3001 is a versatile, lightweight, ergonomically-designed instrument that can support up to four external detectors, each with its own set of calibration and user parameters, used for alpha, beta, or gamma radiation survey. Three modes of operation – RATE, MAX, and COUNT – are available. Measurements can be collected in two sets of units (primary and secondary) for RATE and MAX modes in cps, cpm, Bq, dpm, mR/hr, or μSv/h units. Users can switch between two sets of chosen units by simply pressing the Units button. The DETECTOR button selects the color-coded detector and activates the corresponding color LED.
An internal switch is used to enable or disable the front-panel setup feature to protect desired settings from inadvertent modification. Setup is also available via software available from Ludlum Measurements. This instrument features a large, easily-readable LCD (liquid crystal display), a piercing audio warning tone, and easy, intuitive, user-friendly design.
Splash-resistant construction allows the Model 3001 to be used outdoors. The unit body is made of lightweight, durable, high-impact plastic. The Model 3001 is shipped ready to use with batteries and calibration certificate.
