D-Opto Sensor

The D-Opto sensor is a rugged low power dissolved oxygen sensor.

The low power consumption, and low sensor drift make the D-Opto an ideal choice for remote battery and solar powered installations.

The D-Opto is available with either an SDI-12, 4-20mA or 0-5 volt signal output.

The D-Opto features a rugged interface panel for simple connection to the data logger, and is supplied with D-OptoCom software for calibration and setup.
