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.
The D-Opto interface panel makes installation and connection to a data logger quick and simple and enables simultaneous connection with a computer to ease in-situ calibration and field checks.
For situations where bio-fouling is extreme, the D-Opto can be fitted with the D-Opto Shutter system. Every D-Opto has a copper ring surrounding the optical window to reduce bio-fouling.
