Data Logger Configured with Water Quality Sensor(s)

Eureka Manta Multiparameter Water Quality RecorderEngineered to last for years in the field, the Eureka Manta Multiparameter Water Quality Sonde is ideal for fresh, salt or brackish water monitoring applications. Housed in a tough 3.25" diameter PVC housing, the Manta has 1.5 MB of EEPROM memory and can accommodate water quality sensors for temperature, conductivity, dissolved oxygen, pH, ORP, turbidity & depth/stage. For spot checks, the Manta can be connected to the Amphibian Field Display Unit, or for long term remote monitoring applications, an optional 8 D cell battery pack can be installed.Every aspect of the Manta is designed for increased reliability and durability. For example, in the field, the recessed (less likely to break off) water quality sensors can be quickly and easily replaced while the internal electronics are protected from exposure to the elements. The separate analog and digital boards isolates the circuitry for more accurate data signals and cuts down on repair costs. And the detachable cablelock system minimizes pins or connector breakage, allowing cables to be easily changed while maintaining a sealed system with fewer components, again reducing maintenance and repair costs. The polyurethane cable assembly is substance-filled to prevent water from traveling in the event of a minor cut. And the clear plastic housing allows the user to see if the double o-ring seals have been breached, while LED's on the circuit board provide diagnostic and operational information.Eureka's free Windows-based software guides you through setup, calibration and data download processes. The real-time graphing makes it easy for you to visually recognize when your readings have stabilized, and the calibration log provides a regulatory record of instrument calibration history.Dissolved Oxygen Sensor (Clark Cell)- Changing DO membranes is easy with the snap-on caps which provide uniform stretching for more consistent results and eliminate bubbles and wrinkles. And a built-in magnetic stirrer maintains consistent flow over the D/O sensor.Dissolved Oxygen Sensor (Optical)- Besides its reliable, field-proven design, Eureka
