The newest member of the HydroCAT family of water quality Sondes can also measure pH, turbidity and chlorophyll. By plumbing the pH sensor inline with conductivity, temperature and optical dissolved oxygen the HydroCAT-EP is capable of deployments up to three months without requiring data processing to correct for drift.

With improved optics and built-in adaptive sampling intelligence, the SUNA V2 measures nitrate with industry-leading accuracy and stability over a wide range of environmental conditions. The wide range of optional features offered for the SUNA V2 make the sensor a cost-effective choice for routine nitrate

Field proven sensors measure conductivity, temperature, pressure and optical dissolved oxygen. Depending on the application, the HydroCAT can collect high quality data for up to a year. Excellent bio-fouling protection is provided by US EPA-approved anti-foulant devices, integral pump, and unique internal flow path provides stable measurements throughout a deployment.

The Environmental Characterization Optics (ECO) series of fluorometers delivers both high resolution and wide ranges. The ECO series excels in biological monitoring and dye trace studies. The potted optics block results in long term stability of the instrument and the optional wiper delivers truly long term field measurements.
