They are designed to be disassembled for ease of transportation and storage, and can be set up in five minutes or less without any tools.\u003c\/p\u003e\n\u003cp\u003eEach instrument’s non-volatile parameters are preset at the factory to detect a 1.0 μCi \u003csup\u003e137\u003c\/sup\u003eCs source in a 10 μR\/hr background field. Microprocessor-based electronics provide ease of setup and reliability. Status LEDs indicate count-cycle status and audible signals accompany the LEDs for additional indication. Detector counts, background, and all parameters may be viewed on the instrument display. All setup is accomplished by way of pushbuttons located below the display.\u003c\/p\u003e\n\u003cp\u003eThese portal monitors can be operated in a walk-through mode with a quick scan occurring while a person is positioned within the portal. In this mode, checking is performed every 200 milliseconds while the portal is occupied, and 600 milliseconds before and 600 milliseconds after the portal is occupied. The portal monitor can also monitor in a stop-and-count mode, allowing for a more sensitive scan. In stop-and-count mode, the fixed count time may be set from 1 to 20 seconds.\u003c\/p\u003e\n\u003cp\u003eThese instruments have automatic background update and dynamic alarm setting capabilities. On startup, the instrument will take a background count and calculate alarm levels for each detector. Self-diagnostic routines check the background count and warn if the background becomes either too high or too low.\u003c\/p\u003e\n\u003cp\u003eAlarms are calculated with a user-adjustable sigma parameter and the current background count. During setup, the user can also specify individual alarms only, sum alarm only, or both individual and sum alarm. The sum alarm groups upper detectors and lower detectors.\u003c\/p\u003e\n\u003cp\u003eIncluded with each instrument are a wheeled transport case and a clear polypropylene sleeve to protect against wet weather conditions.\u003c\/p\u003e\n\u003cp\u003eThese instruments are able to operate from 85 to 250 Vac, 50\/60 Hz without a voltage selector switch. They may also be powered from the supplied vehicle cigarette lighter adapter, or three or six “D” cell batteries.\u003c\/p\u003e\n\u003ctable class=\"table table-bordered\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003ePart Number\u003c\/th\u003e\n\u003cth\u003eDetectors\u003c\/th\u003e\n\u003cth\u003eOutside Dimensions\u003cbr\u003e\n(H x W x L)\u003c\/th\u003e\n\u003cth\u003eInside Dimensions\u003cbr\u003e\n(H x W)\u003c\/th\u003e\n\u003cth\u003eTotal Detector Volume\u003c\/th\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e52-1\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e48-3172\u003c\/td\u003e\n\u003ctd\u003e4 side\u003c\/td\u003e\n\u003ctd rowspan=\"2\"\u003e211 x 81.3 x 45 cm\u003cbr\u003e\n(83 x 32 x 17.5 in.)\u003c\/td\u003e\n\u003ctd rowspan=\"2\"\u003e206 x 61 cm\u003cbr\u003e\n(81 x 24 in.)\u003c\/td\u003e\n\u003ctd rowspan=\"4\"\u003e11 L\u003cbr\u003e\n(672 in\u003csup\u003e3\u003c\/sup\u003e)\u003c\/td\u003e\n\u003ctd rowspan=\"4\"\u003eApprox. 32 kg (70 lb),\u003cbr\u003e\n45 kg (100 lb) in case\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Ludlum","offers":[{"title":"Default Title","offer_id":43427729473590,"sku":null,"price":8582.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0649\/9853\/9318\/files\/52-1-full-front-view.jpg?v=1737477560","url":"https:\/\/www.chpconsultants.com\/products\/ludlum-model-52-1-portable-portal-monitor","provider":"CHPConsultants","version":"1.0","type":"link"}
