Model 54

Automating routine contamination frisking using instruments like Ludlum's Small Article Monitor is a well-proven methodology for ensuring that items leaving controlled areas are clean. Ludlum's new Model 54 has adopted time-tested and proven concepts, gathered from throughout the industry, and integrated them into a new, ground-up design that employs the latest computer and detector technologies. The result is a more robust, user-friendly, and cost-effective design than any other currently available.

Central to the design is the detector chamber, which is configured to deliver the largest and most sensitive detection volume presently available for this type of monitor. The specially-designed, large area, 5 cm (2 in.) thick plastic scintillator detectors are arranged to optimize the sensitivity throughout the chamber. A stainless steel liner protects the detectors while facilitating decon. The chamber can be configured with either four or six detectors, and either 2.5 or 5.1 cm (1 or 2 in.) of lead. The lead is shipped separately and easily loaded on site.

The Model 54 is equipped with two doors, which can be mounted with either a left- or right-hand swing. Hardened steel door hinges, securely bolted to the instrument frame, employ ball-bearings to make operating the doors as easy as possible. Very powerful, non-jamming, electromagnet-activated door locks may be configured by the user to support logistics for single or pass-through type operation.

Ludlum's new QPASS algorithms provide a means whereby administrators can optimize the settings best suited for their operations. QPASS additionally surpasses all other technologies via built-in intelligence that can automatically optimize settings as the count begins to deliver the most efficient and effective count possible. It's a perfect balance between minimum count time and maximum sensitivity that affords eliminating a second count to verify any alarms.

Operational status and instrument condition is clearly presented to the operator via a large 30.7 cm (12.1 in.) touch screen LCD. An optional second LCD mounted to the opposite side is available where desired, as in the case of pass-through type operations. The screens are designed to be very intuitive and are accompanied by a large push-button to activate sample counting, and two smaller push-buttons for updating the background or acknowledging any alarms. The main counting screen is locked, with password control access via the touch screen, to either routine check functions at one level or a second level accessing all parameters.

The electronics support the latest Ludlum detector boards, which are connected to a PC-based fan-less controller motherboard running on Embedded Windows™ XP platform. The system also provides an ethernet port that enables connection to the site LAN for collecting all count and alarm data as well as monitoring all activities remotely from one or more locations.

When taken in total, Ludlum's Model 54 Small Article Monitor delivers state-of-the-art technology in a robust design with enhanced performance, user-friendliness, and connectivity at the lowest cost on the market.

Headphone Jack

This modification for survey meters adds a headphone jack to the instrument body so headphones can be used to monitor click-per-event audio and audio alarms. Headphones are helpful when the instrument is being used in areas with high ambient noise levels or in areas where the audio would be distracting to others, such as in a medical or office environment.

Shoulder Strap

This 1.8 m (6 ft) adjustable shoulder strap is a great way to keep your hands free while operating survey meters. The nylon strap with a wide rubber comfort pad can also be helpful for conveying some of the heavier instrument/detector combinations in the field.
