The D-Opto is a rugged low power dissolved oxygen sensor tried and tested in a wide range of extreme environments. A popular choice for both researchers and local government catchment monitoring programs. As the D-Opto measures DO optically, it doesn’t consume oxygen during sampling and can therefore be used in still water without compromising accuracy. It is available with either SDI-12, 4-20mA or 0-5 volt signal output. The low power consumption and low sensor drift make the D-Opto an ideal choice for remote installations.

For harsh environments and situations where bio-fouling is extreme, the D-Opto Shutter system can be fitted to the D-Opto Sensor (not currently available for the D-Opto Logger). The Shutter is a mechanical device that simply attaches to the side of the D-Opto, and is controlled by the same data logger attached to the D-Opto.

The D-Opto Logger is a fully self-contained dissolved oxygen logger, incorporating a dissolved oxygen and temperature sensor, battery and power efficient data logger in a rugged compact underwater housing. Simple to operate and easy to deploy, the D-Opto Logger can endure long field deployments between servicing. The field replaceable 9-volt standard battery and simple software with data graphing function makes field servicing and data downloading quick and straightforward.
