Thermal Anemometer

Rugged, accurate and easy-to-use portable soil data collection

The HydraGO and HydraGO FLEX represent the most advanced portable soil sensor system. Simply insert the probe into the soil, and tap on the “Sample” button in the HydraGO app. The HydraGO and HydraGO FLEX communicate wirelessly with your smartphone or tablet using Bluetooth. Both systems features a rugged, Delran housing that contains a rechargeable battery. The internal battery will last for long field sessions with repeated and frequent data samplings.
