Climatronics - Handheld Expeditionary Meteorological Station (HEMS)
The Hand Held Expeditionary Meteorological Station (HEMS) is a COTS system used to determine surface meteorological conditions. The data can be used in a multitude of applications, both civil and military, anywhere a lightweight, rugged and durable weather station is needed. The system consists of Climatronics’ TACMET II weather station, a rugged personal digital assistant (RPDA), and Climatronics’ HEMS software that runs on the RPDA under the Windows CE 2002 operating system.
The TACMET II weather station is built around Climatronics’ novel Sonimometer wind sensor, and measures the wind speed and wind direction, air temperature, relative humidity, and barometric pressure. An internal flux-gate compass is used to automatically orient the TACMET II wind data to north.
Power for the TACMET II and the RPDA is provided from commercially available batteries. The TACMET II batteries are mounted in the handle. A single carrying case is included to house the sensor, handle, RPDA, and interface cable.
An optional tripod is available to mount the sensor when it will be used in one location for extended periods. An extended case is available to carry all of the system components as well as the tripod when this option is included.
Climatronics` TACMET II Weather Sensor System, P/N 102304 is a second -generation weather sensor, which includes a number of new features now possible with improved sensor technology resulting from our commitment to product improvement. The TACMET II incorporates Climatronics’ new and unique folded -path, low -power sonic anemometer, the Sonimometer , with a temperature sensor, a fast -response, capacitive relative humidity sensor, a barometric pressure sensor and a flux -gate compass. An on -board microprocessor provides an RS -232C digital output.
The TACMET II Weather Sensor System is designed for maximum durability, portability, and utility, making it uniquely applicable for rapid deployment and use by one person under adverse conditions. The sensor may be mounted on a tripod or vehicle mast.
