◀◀ Key Selling Points ▶▶
1. High-Precision Water Potential Measurement
Measures soil water potential (-500 to -10 kPa) with ±1 kPa accuracy (or 1% FS), ensuring reliable data for irrigation and drought management.
Automatic calibration eliminates manual adjustments, maintaining accuracy over time.
2. Zero Drift & Long-Term Stability
No drift caused by ceramic degradation ensures consistent performance, even in harsh environments.
Epoxy-sealed IP68 design withstands extreme temperatures (-40°C to +50°C) and moisture.
3. Plug-and-Play Installation
Simple burial process: Apply mud to the sensor, bury, and start monitoring without programming.
Dual output options: RS485 Modbus-RTU and 4–20mA for seamless integration into IoT or legacy systems.
4. Energy-Efficient & Durable
Low power consumption (15mA@12V DC) ideal for solar-powered or remote setups.
Compact and lightweight (200g), designed for long-term field research.

◀◀ Application Scenarios ▶▶
◆◆ Applications:
Precision Irrigation: Optimize water usage by monitoring soil water potential in real time.
Arid Agriculture: Study drought resistance and crop water requirements in dry regions.
Environmental Research: Monitor frozen soils, roadbeds, and hydraulic conductivity in ecological projects.
Greenhouse Management: Maintain optimal soil moisture for high-value crops.
Hydrology Studies: Analyze soil water properties for flood prevention and water conservation.
Choose RS485 Modbus-RTU for smart farming systems or 4–20mA for traditional setups. Customize sensor networks with flexible addressing and broadcast commands.
◆◆ Install in Minutes, Monitor for Years
Just bury the sensor, apply mud for equilibrium, and start collecting data. Low power consumption keeps it running smoothly in off-grid locations.
◆◆ Equipment Installation
1. First determine the installation depth and location of the soil water potential.
2. Take a soil sample at the installation location, add water and mud to the soil sample, and apply the mud to the soil water potential sensor.
3. The sensor covered with mud is buried to the installation location, and the soil can be backfilled.
