Campbell Scientific EnviroSCAN Probe Specification

The Campbell Scientific EnviroSCAN Probe is a sophisticated soil moisture monitoring instrument designed for precise and continuous measurement of soil water content. This probe utilizes advanced capacitance technology to deliver highly accurate soil moisture data, essential for agricultural, environmental, and research applications. It consists of a series of sensor modules that can be customized in number and spacing to suit specific soil profile depths and conditions, with the ability to accommodate up to 16 sensors along a single probe.

Each sensor module measures the volumetric water content by detecting changes in the dielectric constant of the soil, offering real-time data with minimal soil disturbance. The probe is compatible with various data loggers and telemetry systems, allowing seamless integration into existing monitoring setups. Constructed from durable materials, the EnviroSCAN Probe is designed to withstand harsh environmental conditions, ensuring long-term reliability and performance.

The probe supports multiple communication protocols, including SDI-12, enabling easy data retrieval and management. It operates within a temperature range suitable for most agricultural environments, and its power-efficient design ensures extended deployment in the field. The EnviroSCAN Probe is part of a modular system that can be easily expanded or reconfigured, offering flexibility to adapt to different soil types and research needs. Its precise measurements and robust construction make it an ideal choice for professionals seeking to optimize irrigation practices, improve crop yield, and conduct detailed soil moisture research.

Campbell Scientific EnviroSCAN Probe F.A.Q.

How do I install the Campbell Scientific EnviroSCAN Probe in the field?
