Frequently, contraband is covertly hidden in inaccessible areas, such as walls, tires, bulkheads, empty spaces in cars or boats etc., where direct observation is not possible without time-consuming dismantling, and possibly even causing irreparable damage to the inspected object.Frequently, contraband is covertly hidden in inaccessible areas, such as walls, tires, bulkheads, etc., where direct observation is not possible.

The ruggedized Hitech-Xpose unit has been designed with an ergonomic grip which may be used in either hand, anti-scratch detection surface, integrated safety wrist strap and a large, easy-to-read, illuminated graphical & numerical display. SAS-Hitech-Xpose, as the toughest density meter on the market, does not utilise polycarbonate coating on the display, which is commonly used by other manufacturers. Instead, Corning "Gorilla Glass" lens was utilised, in order to provide a scratch- and shatterproof coating that does not break easily. Engineered for a combination of thinness, lightness, and damage-resistance, it is used primarily as the cover glass for portable electronic devices including mobile phones, laptop computer displays, and some television screens. Corning Inc., says that Gorilla Glass' material's primary properties are its high scratch resistance (protective coating), and its hardness (with a Vickers hardness test rating of 622 to 701) — which allows to obtain thin glass without fragility.

According to the manufacturer - Corning Inc., the main features of Gorilla Glass are: high scratch resistance (protective coating) and hardness (622 to 701 on the Vickers scale). This allows for thin glass devoid of the typical brittleness.

The density meter is lightweight (more than 20 percent lighter than other contraband detectors) and designed for ambidextrous operation. SAS-Hitech-Xpose has two main modes of operation – Survey, for indication of radiation sources in the vicinity and Inspect, for contraband detection, as well as calibration mode offering simultaneous support for multiple devices. Its flexible readout options include a wireless remote display unit for ease of use in tight inspection locations and a USB port for connection with a computer.

The density meter has 3 main modes of operation:

  • Survey - SAS-Hitech-Xpose


    In survey mode, the density meter acts as a radiation survey meter to locate sources of radioactive material, providing real-time, local radiation rate and count. Results are shown in graphical and numeric format.

  • Mode Inspect - SAS-Hitech-Xpose

    Inspect mode

    In inspect mode, SAS-Hitech-Xpose acts a density meter to locate contraband, it incorporates a large CsI (TI) detector for faster scanning, improved penetration, and quicker indication of “hits” triggered by an abrupt change in density. The operator can select to display readings in graphical or numerical format and with or without alarm. There is also an option to display the current reading with background zeroed out.

  • Calibration


    SAS-Hitech-Xpose uses a common, built-in calibration block that enables universal calibration across similar SAS-Hitech-Xpose Contraband Detector models. After calibration, all units will read +/- 2% of each other. The calibration automatically compensates for decay of the source and aging of internal components. The calibration routine runs in under 30 seconds.

The Hitech-Xpose density meter is equipped with software and internal memory to store search data for up to 100 of the most recent scans. Each scan contains the 30 second count rate plus a time stamp. Search data can be uploaded to the user’s personal computer using the Xpose Tools software toolkit.

Technological advantages of Xpose equipment over the competition

    • significantly smaller and lighter
    • ambidextrous, may easily be used with either hand
    • buttons require much less force/pressure to actuate
    • ergonomically designed with “palm swell” to better fit in hand for comfortable all day use
    • holster has safety strap so the unit is secure when crawling under a car or running
    • large, multi-function display with backlight (remains clear even in broad daylight)
    • on-screen graphing to aid in detection of density variations (search mode) or radiation survey (Radscan mode). The graphing feature eliminates the need for a separate external display unit since scan information is stored and displayed on the screen even when switched off
    • “soft” function buttons that guide the user as to what functions the button will activate
    • last reading is held on the display when the search buttons are released
    • search modes cycled at the press of the mode button, no need to turn the unit off to get back to “start”
    • battery life is 2.5x times longer than competitors continuous “ON”
    • easy and tool-free battery change
    • case is made of high impact cast urethane material. Drop tests show that Xpose Survives > 1 meter (3.28 ft) drop onto a concrete floor on all six sides
    • The device's source has been specifically designed to minimize stray doses of radioactivity to user and provide a greatly improved detection signal
    • all solid state construction eliminates the older technology photo multiplier tubes (PMT) and the high voltage necessary with PMTs. This alone makes the density meter far more rugged
    • larger detector surface area to aid in backscatter detection and radiation survey mode
    • utilizes a state-of-the-art processor and electronics for improved reliability, performance and ruggedness
    • comes with a collapsible Xtender for long reach when required, connected by Bluetooth which requires no cables to make the connection (cable connection is available for those requiring this feature)
    • Xpose Xtreme remote display required for use with the Xtender shows all features of the main unit display and is connected by Bluetooth, requiring no cables to make the connection ( cable connection is available for those requiring this feature)
    • real time clock for time stamping surveys for evidentiary and chain of custody purposes
    • Modular construction enables quick repairs
    • USB port for uploading the time stamped scan data to a computer
    • designed for “instant on” - there is no delay between pressing the search buttons and starting a scan
    • no special disposal requirements (Competitors unit requires hazardous waste disposal)
    • not subject to regulatory inspection
    • provides at minimum all the same functions as competitors but greatly enhanced, due to the most modern technological advances being incorporated plus the advanced functions mentioned above
    • developed in 2012 using most current technology, while competitors were developed 20+ years ago
    • developed by one of the largest USA Defense Contractors with sales of $12 Billion+ and 44,000 employees
    • A network of international service centers is currently being deployed
    • ISO 9001:2008 certification
