  • Description :

    Economical online dissolved oxygen controller, 1 or 2 points calibration, 4 to 20mA signal output. The meter is used for monitoring the dissolved oxygen concentration and percentage saturation in the water.

    Features:
    • Economical online dissolved oxygen controller is equipped with a polarographic sensor.
    • 1 or 2 points calibration using the air-saturated water and zero oxygen solution.
    • Manual salinity and barometric pressure compensation improve the measurement accuracy.
    • Automatic Temperature Compensation ensures accurate reading over the entire range.
    • Low and high alarm limits can be set by user and automatically activate an external device.
    • 4 to 20mA output signal meets industry standard.
    • System menu allows setting the 10 parameters, including the number of calibration points,
      measurement unit, alarm limits, hysteresis value, etc.
    • Reset feature automatically resumes all settings back to factory default options.
