The instruments enable long term accurate monitoring of dissolved oxygen levels in streams, rivers, lakes and marine environments with minimal on-site maintenance and servicing. D-Opto instruments are very rugged, and all feature a copper bio-fouling control ring around the sensor window. 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. The D-Opto Logger is a fully self-contained dissolved oxygen logger. It incorporates the dissolved oxygen sensor, temperature sensor, battery and low-power data logger in a rugged compact and easy to deploy underwater housing. The D-Opto Logger can operate for up to 3 months on a single user replaceable 9 volt battery, logging dissolved oxygen saturation (%), content (PPM) and temperature. The D-Opto Logger is supplied with D-OptoLog software for deployment setup, data offload and calibration.

Software: D-OptoLog supplied at no charge D-Opto Shutter For situations where bio-fouling is extreme, the D-Opto Sensor can be fitted with the D-Opto Shutter. The D-Opto Shutter is a mechanical device that simply attaches to the side of the D-Opto Sensor, and is controlled by the same data logger that is attached to the D-Opto Sensor. The Shutter opens when a measurement is required, and closes between measurements so completely protects the optical sensing window from bio-fouling, sediment build up and physical damage.
