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 units, alarm limits, hysteresis value, etc.
? Reset feature automatically resumes all settings back to factory default options.
