Supports Wide Range of External Detectors
95-250 VAC Power Input
Portable Battery Operation
RS-232 Interface to Printer or PC
Introduction
The Model 2200 is a general purpose scaler with an accompanying ratemeter, and is typically used for counting samples. Its rugged design and construction allow both benchtop and portable applications. The wide-ranging AC power supply and internal batteries are capable of powering the instrument upwards of 120 hours. The Model 2200 supports GM, proportional, and scintillator-type detectors, and provides fine adjustment controls for setting the high-voltage and threshold settings.
An adjustable discriminator and an adjustable window allow the user to count pulses within a user specified energy range. This portable unit can be powered by wall current or by four "D" cell batteries. The latter allows for continued operations during power interruptions. An optional printer (Model 4167-386) is available for hard copy archival of wipe test results.
The Ludlum Model 2200 Scaler/Ratemeter is the ideal economic solution for routine sample counting, single channel analyzing and routine radiopharmaceutical related procedures, when used with the
Model 243
well scintillator (NaTl) detector. The Well Counter's 4π geometry and 1.3 cm (0.5 in.) shielding provides excellent sensitivity to higher energy isotopes like
131
I.

Model 180 Radon Flask Detector:
Introduction
The Model 182 Radon Flask Counter is a light-tight sample box that uses scintillation techniques for the detection of radiation material. It consists of a light-tight cylindrical well, a two-inch photomultiplier tube (PMT) optically coupled to a light pipe, and an automatic high voltage On-Off switch.
During sample counting the radon flask is placed on the acrylic light pipe. The upper tube body assembly is held in place with two thumbscrews. A push-rod assembly will then automatically activate a microswitch allowing high voltage (HV) to be applied to the PMT. The HV is automatically disconnected upon removal of the tube. The cover may be removed without turning off the high voltage on the accompanying scaler/count-rate meter type instrument.
The Series "C" connector uses a one-wire system combining the HV and signal. A capacitor located in the tube socket blocks the signal part of the PMT. A terminal strip containing a filter circuit prevents unwanted noise from the microswitch's actuations.
