(PresseBox) - Responding to global demand for improved monitoring of nitrate in freshwater, OTT Hydromet has launched an optical nitrate sensor, the OTT ecoN, specifically for use in environmental surface and groundwater applications. ?This is fantastic news for scientists, catchment managers, water companies, regulators and environmental consultants,? says Peter Schaeffeler, Product Lifeycle Manager at OTT HydroMet. ?In the past, customers have been caught between low-cost/limited-performance sensors and high-end technologies, for which purchase costs prevent large scale deployment. The OTT ecoN neatly fills that gap; as a continuous nitrate monitor, with minimal maintenance requirements, it can be left to monitor in remote locations, and an optional wiper makes it suitable for extended deployments.?

In addition to a low purchase cost, the OTT ecoN also lowers the cost of ownership because it is factory calibrated for life. With automatic drift compensation, zero baseline checks with ultrapure water are quick and easy to perform and are only required as an occasional test of instrument function.

The OTT ecoN measures nitrate by the absorption of UV light at 212 nm and removes the possible effects of organics and turbidity by similar measurements at 254 nm and 360 nm respectively. As an optical sensor, the OTT ecoN provides high accuracy and low resolution without the drift and interferences of ion-selective electrodes, or the ongoing reagent and maintenance costs of wet-chemistry analyzers.

The OTT ecoN can transmit data via an SDI-12 interface due to the new OTT ecoN Modbus to SDI-12 Converter. The converter translates the Modbus protocol for the OTT ecoN nitrate sensor to allow for easy and continuous remote data access. Remote configuration can be achieved as well, to export data and configure the OTT ecoN via a web interface.

No specialized software is necessary to communicate with the OTT ecoN ? a simple, intuitive browser-based user interface is accessed by connecting a small interface unit to the sensor.



Measurements can be stored internally within the sensor, but as a specialist in sensing, datalogging and telemetry, OTT HydroMet can supply the most appropriate monitoring system for every application. This includes the choice of sensor, because the OTT ecoN is available with different cell pathlengths to ensure optimum performance across all measurement ranges. However, OTT HydroMet is also able to conduct a retrospective change of optical path length when customers need to change application, such as moving it from very turbid surface water to groundwater for example.

Summarizing, Schaeffeler says: ?Nitrate is an extremely important contaminant of fresh surface and groundwater; causing health issues in humans and playing a major role in eutrophication and the proliferation of algae. It is therefore essential that the role of nutrients is fully understood and that water professionals are able to access accurate, reliable data on nutrient sources and loading, as well as being provided with alarms when pollution events take place.

?The OTT ecoN has proven extremely accurate and reliable in the field, and has been priced for extensive deployment, so we are very excited with the prospects for this technology.?

The globally operating OTT HydroMet can look back on more than 500 years of combined expertise across seven strong brands that have come together to provide reliability and sustainability for monitoring networks. The company has its headquarters in Kempten, Germany and is the leading provider of complete hydrometric systems for performing hydrological and meteorological measurements. With the recent additions of SUTRON Corporation (2015) G. Lufft GmbH (2016) and Kipp & Zonen (2017), OTT HydroMet offers the broadest portfolio of trend-setting measurement and communication technology in the fields of water quality, water quantity, meteorology, data management and telemetry, the company contributes sustainably to protecting the environment and lives.
