Fast Optical Dissolved Oxygen Meter

Galvanic electrode dissolved oxygen (DO) sensors have been developed for several decades but have had been problematic in the field because they have slow response times, typically 25-50 seconds and measuring DO at baseline levels is not very accurate. The Rinko is a fast-response, high accuracy & high resolution dissolved oxygen, based on new optical measurement.Typically the Rinko has a response time of <1 second,approx. 10 times faster than any other DO sensor available with excellent signal resolution and accuracy. The fast response time makes this unit particularly useful for water profiling where both the downward and upward cast measurements can be used to provide replicates at the same depth. The new Rinko model has been tested to 6,000 metres.
