M3030P_left view open drawer

The 3030P’s 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 EPRI guideline for detecting a few dpm of alpha amidst a several hundred thousand dpm beta background.  All data are automatically logged and easily retrievable via a USB connection.  The light weight and battery operability afford convenient use out in the field.  With the optional detector shield, the Model 3030P can be used virtually anywhere.

The instrument comes with a 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.

M3030-Rt-Angle

The Model 3030 Alpha Beta Sample Counter incorporates an internally housed ZnS(Ag)plastic scintillator detector with shielded 5.1 cm (2.0 in) diameter stainless steel sample tray and scaler/counting electronics into a self-contained, portable system.   This instrument supplies independent backlit LCD readouts to support discriminated alpha and beta sample counting. Key features include background subtraction, crosstalk correction, separate alpha/beta 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 eight hours.

2000_44-88_180-24

The Model 2000 Scaler Counter electronics in combination with the Model 44-88 GM Pancake Detector and Model 180-24 Sample Tray produce an excellent general purpose, low-cost sample counting system.  The scaler reading is presented on a digital, six-digit readout LED that can be set to count from 0.1-999 minutes (or seconds).  An RS-232 port facilitates connection to a PC for recording and control or a printer for direct output of the count results.

The Model 44-88 GM pancake has a 15 cm2 active area, a background of approximately 60 cpm, and 4π efficiencies of: 5% - 14C; 22% - 90Sr/90Y; 19% - 99Tc; 32% - 32P; 15% - 239Pu.  The Model 180-24 tray accommodates samples up to 5.1 cm (2 in.) in diameter and is
designed with slots for setting the tray at 0.32, 0.64, 1.3, 2.5, and 5.1 cm (0.13, 0.25, 0.5, 1.0, and 2.0 in.) from the detector.

2000_43-10

The Model 2000 Scaler Counter electronics in combination with the Model 43-10 Detector creates a versatile and simple-to-use alpha counting system.  The scaler reading is presented on a digital, six-digit readout LED that can be set to count from 0.1-999 minutes (or seconds).  An RS-232 port facilitates connection to a PC for recording and control or a printer for direct output of the count results.

The Model 43-10 sample head accommodates up to 5.1 cm (2.0 in.) diameter samples and features a ZnS(Ag) detector detecting a background of 3 cpm or less and a 4π efficiency of 37% to 239Pu.
