Stealth Computer is releasing its new Model TT-840 rugged, environmentally sealed, LCD monitor that can survive in harsh environments. The Stealth model TT-840 is an 8.4inch sunlight-readable LCD that is encapsulated in a rugged aluminium enclosure that is sealed to IP68/NEMA 6P. The high-performance LCD is totally water-tight, surviving liquid, dust and dirt intrusion. Stealth's rugged LCD will operate in extreme temperatures from -20 to +60 degrees C, making it suitable for use outdoors and in intense weather conditions.

Stealth's CEO, Ed Boutilier; states: "By capitalising on the latest in LED backlight technology, the Stealth TT-840 rugged LCD features a vivid sunlight-readable display with up to 1000 nits of brightness and a 600:1 contrast ratio, making it ideal for outdoor or high ambient light conditions." The LED backlights are said to provide superior performance over their CCFL counterparts by offering low power consumption, long operating life and increased protection against vibration and shock.

The TT-840 display is shipped as standard with infrared touchscreen technology, which Stealth says provides distinct advantages over other touchscreen technologies. Benefits include accurate touch positioning, increased optical transmissivity, superior shock and vibration specifications, no drift calibration, and the ability to operate in wet environments with or without gloves.

Stealth's TT-840 LCD monitor operates with a 12-36VDC power input, making it suitable for DC-powered applications typically found in mobile applications. Power, video and USB connections are provided through IP68 waterproof connectors directly on the unit. A wide range of versatile mounting options is available by using the industry-standard VESA and RAM mounting patterns.
