GAUSS METER The 3030P with a solid state PIPS™ detector facilitates efficient and cost-effective, simultaneous alpha and beta sample counting for air filters, smears, and swipes. This instrument meets the newer Electric Power Research Institute (EPRI) guideline for detecting a few disintegrations per minute of alpha amidst several hundred-thousand disintegrations per minute beta background. All data are automatically logged and easily retrievable via a USB connection. The light weight and battery operability afford convenient use in the field. With the optional detector shield, the Model 3030P can be used virtually anywhere.   The instrument comes with PC control software that allows the user to set all parameters, view QC check settings, change alpha and beta window and threshold values, perform MDA (Minimum Detectable Activity), and retrieve the sample data saved to the logging memory.   Features Fully Integrated Alpha-Beta Sample Counter Simultaneous Alpha and Beta Counting Employs PIPS™ Detector Ultra Low A/B Crossover & Backgrounds Adjustable Alpha Window for Radon Rejection Data Logging with USB Connectivity 48-Hour Battery Operation Includes PC Software   Detector Solid-state silicon detector Active and Open Area 1700 mm2 Alpha Efficiency (4π) 239Pu 35% Beta Efficiency (4π) 99Tc 15% 137Cs 23% 90Sr/90Y 34% Background  (10 µR/hr field) Alpha 3 counts in 10 minutes, or 0.3 cpm Beta 300 counts in 10 minutes, or 30 cpm Crosstalk  (10 µR/hr field) Alpha ≤ 5% Beta ≤ 0.1% Sample Size Capable of holding 2.5 cm (1 in.) or 5.1 cm (2 in.) diameter samples (with provided insert), up to 1.02 cm (0.4 in.) thick Scalers Two each (one per channel), six-digit LCD displays with backlights providing a range of 0 to 999,999 counts (started by COUNT button) Count Timer Single timer, switch adjusts from 0.1 to 60 minutes (.1, .5, 1, 2, 5, 10, 60) or selects PC (PC is a user-customizable setting that allows user-defined counts from 0.1 to 546.1 minutes) Alarm Alpha, beta, and alpha + beta alarms are user-settable Status Indicators QC Daily Quality Check needed LOW BATT Battery power is low CPM/DPM Counting in CPM or DPM mode αAL/βAL Count has exceeded alarm set point Background Subtract May be subtracted automatically in either CPM or DPM modes Interface USB - includes a 1 meter (39 in.)
