POGO Portable Soil Sensor

Description

The POGO Portable Soil Sensor puts the power of the popular Stevens Hydra Probe II in the palm of your hand. Featuring Stevens Hydra- Mon PDA software, you are free to take soil measurements anywhere at any time, without the time requirements of setting up a permanent soil monitoring system.
With the Stevens HydraMon software, taking soil readings is easy. Simply insert the probe into the soil, select the correct soil type from the menu, and click the “Sample” button on your PDA’s screen. The software will display soil temperature, conductivity and dielectric permittivity on-screen for immediate viewing. The user also has the option to log all sensor measurements to a file with user-defined physical locations.
The PDA can be synchronized and readings

automatically downloaded to a PC as a CSV or text file for further data analysis in MS Excel.
Any PDA with Windows CE can be connected to the POGO via a serial adapter cable, allowing the Hydra Probe II to communicate directly with the PDA.
The POGO system features a rugged, anodized aluminum housing that contains a rechargeable battery pack that powers the Hydra Probe II. The POGO also has an LCD screen that indicates battery voltage as well as an on/off switch. A strap allows the POGO to be carried over the shoulder, allowing the PDA to be easily operated with two hands while conducing soil measurements.
