Air Scan AS-2000

The Model AS-2000 Modular Weather Station is a computer-based meteorological system designed as a “user-friendly” solution for data storage and real-time monitoring of weather conditions.  The standard package includes:

  • Wind Speed
  • Wind Directions
  • Air Temperature
  • Relative Humidity
  • Barometric Pressure
  • Precipitation
  • Data Logger
  • Tripod & Mast
  • Solar Radiation Shield for temp/humidity
  • Cables & Mounts
  • Set-Up Disk

Additional Sensor options include solar radiation, water or soil temperature, auxiliary air temperature, rain gauge upgrade, evaporation and soil moisture.

The unique modular system design provides plug-and-play functionality for adding or replacing sensors.  The AS-2000 Data Acquisition Module  includes the following features larger nonvolatile memory, selectable averaging intervals, 12 bit analog conversion, 0.1% F.S. accuracy, two alarm outputs, and optional modem communications.

The AS-2000 is supplied with an attractive desktop data acquisition module with a memory capacity of 128KB RAM (approximately 45 days at 15 minute intervals with 6 sensors).  The standard system includes a 120Vac power adapter and RS232 serial port for connection to a personal computer.  For outdoor or remote applications, two enclosure options are available.  One is for sites with AC power and the other utilizes a solar panel.  Both options include a NEMA-4X enclosure and rechargeable battery to allow continued operation in the event of power failure.

Data can be viewed using Windows HyperTerminal or other terminal programs such as Procomm.  A one page real-time text display or an ASCII row and column format may be selected.  A menu is provided for setting the date and time, alarms, logging interval etc. Optional graphical displays software is available for viewing real-time and historical data charts and graphs.
