Ludlum Model 3030E with Model 43-10-1

Alpha/Beta Radiation Sample Counter

Introduction

Ludlum Model 3030E with Model 43-10-1 Alpha Beta Radiation Scaler ● Alpha/Beta Sample Counter with External Detector

● Simultaneous Alpha and Beta Radiation Counting

● Utilizes ZnS(Ag) on Plastic Scintillation Detector

● CPM and DPM Modes

● Background Subtraction

● Independent Readouts and Alarms

● 8 Hour Battery Operation

● RS-232 Interface

● Includes PC Software

This system joins Ludlum's Model 3030E dual channel radiation scaler with its Model 43-10-1 dual phosphor radiation detector/2 in. (5.1 cm) diameter sample tray to produce a complete alpha beta radiation sample counting system. The Model 3030E electronics incorporates independent backlit LCD readouts to support discriminated alpha and beta sample counting. The system features background subtraction, crosstalk correction, separate alpha/beta radiation alarms, CPM/DPM operating modes, and a pre-scripted QC function with automatic reminder timer. The instrument supports both 110 and 220 VAC operation and includes a trickle charged gel-cell battery for portable offsite use up to 8 hours. A wide range high voltage power supply supports virtually any detector. Status indicators located along the front panel inform the operator when another QC check is required, if the detector is non functional, if it's operating in DPM or CPM mode, and if either an alpha or beta radiation alarm setpoint has been exceeded.
