Model WLS-8000 -Industrial Weather Station

The Model WLS-8000 Weather Station is an industrial-grade, digital computer station. It features the very finest, high-resolution sensors available: The Texas Electronics Wind Direction and Speed Sensor, their most precise rain collector, as well as TWI LOG software for you PC. This system is fully addressable by PC via RS-232 modem (supplied) and automatically logs data to memory. The system includes: WLS Console, wind speed and direction sensors (instant and average), barometric pressure, Solar Radiation, Rainfall (daily and monthly plus rate), temperature and humidity sensor in pagoda shield, Serial RS-232 cable and mast junction box, 120` sensor cables to junction box and TWI logging software. The system also provides time and date, English or Metric, computes wind chill, heat indices and dewpoint, and maintains daily minimums and maximums. The TWI LOG program can network with up to 256 other WPS, intelligently download that data into separate files and/or calibrate and maintain the units remotely. The handsome console features a non-volatile memory and clock and a large digital display. Console measures 12"W x 7"H x 6"D. Barometer: 24.00" - 32.00" hg.; Wind Speed: 0-120 mph; Temp: -70 to 140 degrees F; Humidity 0-100%; Solar Radiation 0-1400 W/m2; Rainfall: 0.00-999 inches. 12-hour uninterruptable power supply.
