Description

Factory calibration and streamlined reference checks enable users to generate scientifically defensible data with minimal time and money spent on field maintenance.  A five-year warranty and a set annual service cost means users can easily predict and plan for their service costs during the first five years of use. Ideally suited for long term deployments the HydroCAT-EP can be easily integrated with external data loggers and telemetry systems.

Specifically designed for long term deployments in remote, biologically rich environments it comes equipped with multiple anti-fouling systems. Most sensors, including pH, are protected within the unique internal flow path by EPA-Approved anti-foulant devices. An integral pump minimizes the sensors exposure to environmental waters significantly reducing the impact of bio-fouling on sensor performance and drift. A copper faceplate and wiper protect the combination chlorophyll and turbidity sensor.

The HydroCAT-EP uses the Universal Coastal Interface (UCI). This easy to use software can also be used with the SUNA V2.  Multiple task wizards and features like an automatic battery endurance calculator make it easy for anyone from novice water quality professionals to senior experts to quickly learn how to use it.


Feature

  • Low total cost of ownership: Annual calibrations, a five year warranty, and deployment durations of three months mean less cost to service and maintain over the life of the instrument.
  • Data Reliability: With the exception of pH all sensors are factory calibrated in a temperature-controlled bath that operates at 2 -4 times the accuracy of the instrument
  • Easy to service: The pH sensor is a smart sensor that can be hot swapped in the field minimizing the need for in field service and calibration.
