Handheld anemometer - meteorological station RVM 96C

Measurements of:

  • wind speed and direction

  • temperature

  • atmospheric pressure

  • relative humidity

  • horizontal orientation

    Highlights:

  • built-in electronic compass; accurate wind direction data without need for instrument orientation

  • illuminated LC display, capable of presenting current and historic data in numeric and graphic way

  • built-in storage of statistic data in the permanent internal memory (EEPROM) for 2048 intervals; data are not lost even when battery is empty or removed.

  • built-in calculations of mean values and extremes

  • serial data transmission to the external computer

  • scalar or vector wind processing

  • rechargable Li-ion battery.

    Handheld anemometer – meteorological station RVM 96C is truly portable, easy to use instrument for basic field meteorological measurements. It is used in all cases, where other instruments, due to their design, weight, or dimensions, are unsuitable.

    When in basic mode, RVM 96C shows on it`s graphic LCD, depending on the selection, one of the following types of measured data:

  • instant data

  • average data for the selected interval

  • minimums for the selected interval

  • maximums for the selected interval

Operation parameters are selected and set through the menu-organized comands. Settings and constants are stored in EEPROM, so that they are unchanged when instrument is switched off, even when battery is removed.

At the end of each data processing interval, mean values and extremes are stored with the time stamps in the EEPROM data storage. These data can be reviewed later on the instrument display or transmitted serially to the external computer. RVM 96C can store data for up to 2048 data processing intervals. This means, that data for 85 days are stored, provided that averaging interval is set to 1 hour. Data are stored on FIFO (first in – first out) principle.

System for measuring wind speed is optoelectronic, with 3-cup Robinson’s cross. Direction is also measured digitally (6-bit Gray code), corrected automatically to the true wind direction by built-in electronic compass.

RVM 96C can measure wind speed in m/s, km/h, knots, or mph, and temperature in oC or oF.

Lid of a handle has standard ¼” nut to enable the attachment of the device to the standard photographic tripod.

 

There is also an optional bluetooth conection with android devices so you can view the real-time or saved data on them. The application can be transfered from: www.ames.si/files/RVMDisplay.apk or by using the following QR code:
