The D-Opto range of dissolved oxygen instruments are based on a field proven optical technology that has been successfully used for many years. 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.
The D-Opto Sensor is a rugged low power dissolved oxygen sensor available with either SDI-12, 4-20mA or 0-5 volt signal output. The low power consumption and low drift make it an ideal choice for remote installations.
The D-Opto Logger is a fully self-contained dissolved oxygen logger. Simple to operate and easy to deploy, the D-Optologger can endure long field deployments between servicing. The field replaceable battery and simple software with data graphing function makes field servicing quick and straight forward.
The Hydro-Wiper is an innovative mechanical wiper system, with versions available for a wide variety of underwater instruments. Using a regular gentle brushing action, the Hydro-Wiper keeps the sensing window of the instrument clean from bio-fouling and unwanted deposits such as mud. The Hydro-Wiper reduces the need for costly site visits to manually clean the instrument.
