	Ludlum Model 177 (48-1632) Ratemeter - Pre-owned.........$760 each The Model 177 is a rugged benchtop ratemeter with alarming capability. These units are useful for frisking operations at stations where line power is available but can also be used in portable applications for up to 50 hours using the internal rechargeable battery.The Model 177 supports GM and scintillation detectors and displays the results on a linear readout analog meter. Probe is not included.
	Ludlum 44-9 Pancake G-M Probe - Pre-owned................... $210 each The GM pancake-type detector encapsulated in the Ludlum Model 44-9 is suitable for general purpose survey of alpha, beta, and gamma radiation. This detector operates between 850 to 1000 volts, and is compatible with any Ludlum instrument capable of supplying 900 Vdc and an input sensitivity of 30 mV or higher.
	Ludlum Model 9 Ion Chamber - Pre-owned.....................$1295 each The four range Model 9 is used for general purpose survey. The meter includes an air ion chamber and a retractable beta shield. The total counting range is from 0 - 5000 mR/hr. The energy response is within plus or minus 20% of true value from 10 keV - 2 MeV. Response time is typically 3 seconds from 10% to 90% of final reading.
	Ludlum Model 12 SA MicroR Meter - Pre-owned.............$970 each The Model 12SA is a high sensitivity gamma MicroR/meter with alarm employing an internally housed 2.5 cm (1 in.) diameter by 2.5 cm (1 in.) thick NaI detector. The design offers an industrial robustness and quality that promotes long-lasting protection and instrument life. The front panel additionally includes an alarm lamp, which is accompanied by an audible output anytime the alarm setpoint is exceeded.
	Ludlum Model 12 Survey Meter- Pre-owned.....................$670 each This general purpose, handheld analog ratemeter supports GM, proportional, and scintillation detectors. The front panel controls include a rotary switch for selecting the four-decade range, instrument shut-off and battery test, an audio on/off switch, a fast/slow response switch, a high voltage display button, and a count reset button.
	Ludlum 44-92 Beta / Gamma Detector pre-owned............$1295 each The Model 44-92 probe is useful for low-level beta gamma survey. Suggest instruments include models 12, 2000, 2200, 2221, 2350-1, 177-61. The detector is a sealed, xenon gas proportional. The active window area is 169 cm2, open: 140 cm2. The density is 6.0 mg/cm2 titanium. The 4 pi efficiency for the following isotopes is: 10%-14C; 13%-99Tc; 24%-36Cl; 26%-90Sr/90Y; 3%-129I; 1.6%-57Co; 1.2%-55Fe; 10%-239Pu.
	Ludlum 2200 Scaler (48-1651) SCA- pre-owned................$1418 each The Model 2200 is a general purpose scaler with an accompanying ratemeter, and is useful for counting samples, single channel analyzing, and routine radiopharmaceutical related procedures. The Model 2200 supports GM, proportional, scintillation 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.
	Ludlum 243 Shielded Well Counter - pre-owned..............$1589 each The Model 243, along with a pulse height analyzer system, is used for gamma ray assay and wipe test analysis. The Model 243 is shielded with 1.3 cm (0.5 in.) of lead to improve sensitivity by reducing background and other external radiation. The detector is an integrated 4.5 x 5.1 cm (1.8 x 2 in.) (Dia x thickness) NaI (Tl) crystal scintillator optically coupled to a 5.1 cm (2 in.) diameter, 10-stage photomultiplier tube.
