Hydra ProbeⅡ Soil three-parameter sensor

The Hydra Probe II is a new three-parameter soil sensor from Stevens. An upgrade of the original Hydra Probe soil three-parameter sensor, the Hydra Probe II soil sensor provides increased measurement accuracy and supports SDI-12 and RS-485 communication protocols, giving you more choices. Unlike other soil sensors, the Hydra Probe Ⅱ soil sensor combines a variety of measurement elements in one measurement to obtain soil moisture, conductivity, salinity and soil temperature data, saving you a lot of valuable time.

The Hydra Probe II uses a compact integrated design, excellent design and superb manufacturing process to adapt to long-term field measurement work without special maintenance.

Product characteristics

• Simultaneous measurement of soil moisture, conductivity, salinity and soil temperature
• It can adapt to the high saline-alkali soil environment
• Instant response, fast measurement
• It has been tested by practice for ten years and the technology is mature
• Good compatibility with most data collectors
• Compact design, easy to carry, durable
• Easy to use, maintenance-free
