Basic Information

Observ-Met is a specifically designed meteorological Equipment to cater all the present day requirements of Meteorological observations. Its low power operation makes it suitable for remote Data Acquisition applications. The in built graphical LCD display along with user friendly interaction menus makes the settings, configuration and viewing the stored data very easy for the user. User can continuously view and monitor all the readings or can view the stored data values on the graphical LCD display.

The Observ-Met can store 10 years of 1 minute sampled data into its internal flash memory. The stored data can be downloaded on a PC using a user friendly customized PC software provided with the system. The stored data can be directly printed in numerical as well as graphical format on a stand alone 80 column Dot Matrix Printer interfaced directly to the Observ - Met.

The stored data can be backed up by connecting a USB stick to the USB port provided on the Observ - Met. The backed up data can be then downloaded and viewed on the PC by using the PC software provided with the system.
