D-Opto Optical Dissolved Oxygen Sensors products

The D-Opto sensor – which measures temperature, dissolved oxygen saturation and dissolved oxygen content in liquids – is an indispensable tool for environmental monitoring and research.

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.

The D-Opto Shutter system has a self-monitoring on-board intelligence that ensures reliable operation of the sensor by covering the the optical window between sampling – opening only when a sample is taken. 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.
