This monitor requires an external probe and has a type \"C\" connection.  The unit has variable high voltage and can accommodate energy compensated GM detectors, scintillation detectors, etc.  The range measured is dependent upon the type of detector that is attached.\u003c\/p\u003e\n\u003cp\u003eIt features a wall-mount chassis and a four-digit LED display that is readable from 30 feet. Backlit indicators warn of low radiation (yellow), high radiation (red), instrument failure (red), and low battery (yellow), along with an alarm. A green status light is a positive indication of instrument operation.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #000000;\"\u003eINDICATED USE: gamma monitoring\u003c\/span\u003e\u003cbr\u003e\n\u003cspan style=\"color: #000000;\"\u003eCOMPATIBLE DETECTORS: GM, proportional, and scintillation\u003c\/span\u003e\u003cbr\u003e\n\u003cspan style=\"color: #000000;\"\u003eDISPLAY: 4-digit LED display with 2 cm (0.8 in.) character height\u003c\/span\u003e\u003cbr\u003e\n\u003cspan style=\"color: #000000;\"\u003eDISPLAY RANGE: 000.0 to 9999 (Series One: 00.00 to 9999)\u003c\/span\u003e\u003cbr\u003e\n\u003cspan style=\"color: #000000;\"\u003eOPERATING RANGE: 1 μSv\/h to 10 mSv\/h (0.1 mR\/hr to 1 R\/hr)\u003c\/span\u003e\u003cbr\u003e\n\u003cspan style=\"color: #000000;\"\u003eDISPLAY UNITS: can be made to display in μR\/hr, mR\/hr, R\/hr, μSv\/h, mSv\/h, Sv\/h, μrem\/hr, mrem\/hr, rem\/hr, cpm, cps, and others\u003c\/span\u003e\u003cbr\u003e\n\u003cspan style=\"color: #000000;\"\u003eLINEARITY: readings within 10% of true value with detector connected\u003c\/span\u003e\u003cbr\u003e\n\u003cspan style=\"color: #000000;\"\u003eRESPONSE: typically 3 seconds from 10% to 90% of final reading\u003c\/span\u003e\u003cbr\u003e\n\u003cspan style=\"color: #000000;\"\u003eINDICATORS:\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003eSTATUS: (green light) instrument functioning properly\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003eLOW ALARM: (yellow light and slow \u0026lt;1 per second\u0026gt; beep) can be set at any point from 0.0 to 9999\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003eHIGH ALARM: (red light and fast \u0026lt;4 per second\u0026gt; beep) can be set at any point from 0.0 to 9999\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003eDET FAIL: (red light and audible tone) for conditions of detector overload, no count from detector, or instrument failure\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003eLOW BAT: (yellow light) indicates less than 2 hours of battery power remaining\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003eOVERLOAD: display reading of -OL- and audible FAIL alarm indicate detector saturation\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003eOVER-RANGE: display reading of “----” and activated low and high alarms indicate that the radiation field being measured has exceeded the counting range of the instrument (or when dead time correction accounts for more than 75% of the displayed reading)\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eREMOTE (optional): allows for connection of Ludlum Model 271 or 272 remote units\u003cbr\u003e\nCONNECTOR: series “C” (others available)\u003cbr\u003e\nETHERNET (optional): 10 Base-T connection for use with Ludlum’s software\u003cbr\u003e\nCALIBRATION CONTROLS: accessible from the front of instrument (protective cover provided)\u003cbr\u003e\nHIGH VOLTAGE: user-adjustable from 200 to 2500 volts\u003cbr\u003e\nDEAD TIME: user-adjustable to compensate for dead time of the detector and electronics (can be read off the display)\u003cbr\u003e\nAUDIO: can vary from approximately 68 dB to 100 dB through operation of the external rotary baffle and the internal voltage connection\u003cbr\u003e\nRS-232 OUTPUT: a 2-second dump for computer data logging\u003cbr\u003e\nPOWER: 9 Vdc wall-mount adapter with four sets of prongs for almost any style wall receptacle\u003cbr\u003e\nBATTERY LIFE: typically 48 hours in non-alarm condition; 12 hours in alarm condition\u003cbr\u003e\nBATTERY CHARGER: battery is continuously trickle charged when the instrument is connected to line power and turned on\u003cbr\u003e\nCONSTRUCTION: aluminum housing with ivory powder-coat finish\u003cbr\u003e\nTEMPERATURE RANGE: -15 to 50 °C (5 to 122 °F); may be certified for operation from -40 to 65 °C (-40 to 150 °F)\u003cbr\u003e\nSIZE: 18.7 x 24.6 x 6.4 cm (7.4 x 9.7 x 2.5 in.)
