Sutron Corporation Books $2,641,160 July 2006.

STERLING, Va. -- Sutron Corporation (NASDAQ:STRN), a leading provider of hydrological and meteorological monitoring products, systems and services, is pleased to announce the receipt of customer orders totaling $2,641,160 in July 2006. The following orders were the most significant:

1.  A $676,757 order from the US Army Corps of Engineers to
        modernize five locks in the New Orleans area. Reliable
        real-time monitoring of these locks is vital for managing risk
        during the 2006 hurricane season. By providing expertise,
        systems and services to monitor, warn and control flood and
        storm surge factors, Sutron is playing a key role in securing
        critical infrastructure in the affected area.

    2.  A $657,400 order from the US Geological Survey's HIF for
        Sutron's GOES Satellite Transmitter/Logger, SatLink2, and
        various sensors for measuring water level. This order is
        primarily to replace equipment damaged as a result of
        Hurricane Katrina in Alabama, Mississippi, Louisiana, and
        Texas.

    3.  A $299,406 order from NOAA's National Ocean Survey for 16 Tide
        Gauges and associated sensors.

    4.  A $234,864 order from NOAA's National Data Buoy Center (NDBC)
        for 36 units of Sutron's 40 Watt GOES Satellite
        Transmitter/Logger, SL2-B40W, to be installed on NDBC buoys to
        gather and transmit real-time data from stations in the
        Atlantic Ocean, Pacific Ocean and the Gulf of Mexico.

    5.  Additionally, Sutron was awarded two Small Business Innovation
        Research (SBIR) Phase I Contracts from NOAA's NOS/NMFS/OAR
        acquisition division. The first SBIR, totalling $94,479, calls
        for Sutron to develop a prototype (preliminary design and
        specifications) for a "DCPI Low Power and Low Cost Command
        Receiver". The new DCPI (Data Collection Platform with
        Interrogate Capability) employing DS-CDMA RF transmission
        techniques will allow two-way communication through the GOES
        Satellite System and other Geostationary Satellite Systems.
        Receipt of the Phase I award and anticipated receipt of the
        2007 Phase II award to continue SBIR DCPI design significantly
        reinforce Sutron's dominance of the global weather satellite
        transmitter/receiver market.

        The second NOAA SBIR received by Sutron in July, $94,380, is
        to innovate an "Improved Water Level Measurement System", and
        calls for Sutron to produce an improved design of the
        dual-orifice bubble gauge for water level observations in cold
        regions. The enhancements will consist of adding capabilities
        to use optimized true-differential sensors and specialized
        processing to increase accuracy, particularly in the presence
        of water waves.

    6.  A $181,956 order from the US Army Corps of Engineers, Tulsa
        District, for GOES Satellite Transmitter/Loggers, SatLink2's,
        and various sensors for measuring water level and
        meteorological parameters.

Sutron designs, manufactures, installs and supports solutions for hydrological, meteorological and coastal/oceanic systems monitoring water level, water quality, flooding, coastline and tidal parameters, weather, dam safety and hydropower. Sutron's customers include Federal Agencies such as the US Geological Survey, the National Oceanic and Atmospheric Administration, the Army Corps of Engineers and the National Weather Service.
