• Cup anemometer, available for the outside airspeed measurement and recording.
• The Cup probe is a built-in tripod fix nut.
• Air velocity: m/S, Ft/min, Km/h, Knots, Mile/h,
• Air temperature ( ‘”, ‘ )
• Type K, Type J thermocouple thermometer.
• A manual datalogger is available ( set the sampling time to 0 ), during execute the manual datalogger function, it can set the different position ( location ) No. ( position 1 to position 99 ).
• Innovation and easy operation, the computer does not need to set up extra software, after executing datalogger, just take away the SD card from the meter and plug in the
• SD card into the computer, it can download the all the measured value with the time information ( year/month/date/ hour/minute/second ) to the Excel directly, then the user can make the further data or graphic
  analysis by themselves.
