The Ludlum Model 2200 is a general purpose radiation scaler with an accompanying ratemeter, and is typically used for counting samples. Its rugged design and construction facilitate 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 radiation 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 hardcopy archival of wipe test results. ●   General Purpose Radiation Scaler/Ratemeter
