Eureka Amphibian Field Display Unit

At about half the price of other sonde field displays, the Eureka Amphibian utilizes commercially available technology to provide a cost-effective solution for real-time monitoring applications. The waterproof, crushproof case meets military specifications and houses a Pocket PC and rechargeable battery pack. The on-board Eureka software provides all the features you need in the field to setup, display readings, and calibrate, the Eureka Manata Multiparameter Sonde.

With a few taps on the screen, you can set up rolling displays of data, capture a frame of data, start a timed log, and average your data readings. Plus the Pocket PC comes with Pocket Word and Excel, and can manage your contacts and address book. Data is automatically transferred to your desktop when you connect, and the free Eureka desktop software allows you to quickly graph and view your data.

The Amphibian comes complete with an Armor 3600 case with lifetime warranty, 9.6 volt rechargeable nickel metal hydride battery pack, battery charger, Sync cable and your choice of PDA: HP iPAQ 1710 - base model or HP iPAQ 2110 - deluxe model with Bluetooth.


Amphibian Specifications:

External Dimensions (inches): L 8.5 x W 5.2 x D 3.125
Weight: 2.6 pounds with batteries and PDA
Buoyancy: Positive (floats)
Battery Life: 20 hours of continuous use
