AKTAKOM ATE-3012 DISSOLVED OXYGEN METER with SD CARD DATA LOGGER is a step forward in the field of precision measurement. Although this meter is a complex and delicate instrument, its durable structure will allow many years of use.


  • Precision dissolved oxygen measurement
  • Dissolved oxygen: 0 to 20mg/l.
  • Dissolved oxygen meter use the polar graphic type oxygen probe with temperature sensor, high precision measurement for Dissolved Oxygen (DO) and temperature measurement.
  • Heavy duty dissolved oxygen probe, probe head can connect with BOD bottle.
  • DO use the automatic Temp. compensation.
  • DO meter build in "% SALT" & "Mountain Height" compensation value adjustment.
  • Separate probe, easy for operation of different measurement environment.
  • Real time SD memory card Datalogger, it Built-in Clock and Calendar, real time data recorder , sampling time set from 1 sec to 8 hour 59 min. 59 sec.
  • 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, computer is not need to setup extra software, after execute datalogger, just take away the SD card from the meter and plug in the SD card into the computer, it can down load the all the measured value with the time information (year/month/date/ hour/minute/second) to the Excel directly, then user can make the further data or graphic analysis by themselves.
  • SD card capacity: 1GB to 16GB.
  • LCD with green light backlight, easy reading.
  • Can default auto power off or manual power off.
  • Data hold, record max. and min. reading.
