Jingli KL-S201 Soil Water Potential Sensor Introduction

KL-S201 User Manual

The Jingli KL-S201 Soil Water Potential Sensor utilizes advanced sensing technology and six-point factory calibration, delivering outstanding measurement accuracy and stability. Unlike traditional water content sensors, it not only indicates how much water is in the soil but also determines whether this water is available for plant uptake and its movement trends. Furthermore, this sensor is not limited by soil type, supports data comparison across different regions, and greatly expands its application scenarios.

Core Features

Full-Range Measurement: Covers -5 kPa to -100,000 kPa, reliably measuring from wet to air-dry conditions.

High Precision Sensing: Six-point calibration ensures accurate readings, with an accuracy of ±(10% of reading + 2 kPa).

Rugged and Durable: Epoxy coating provides protection, adapting to harsh environments and resisting freezing.

Plug-and-Play: Supports the SDI-12 communication protocol for easy integration into various data acquisition systems.

Low Power Design: Typical operating current is only 5mA, ensuring energy efficiency.

Synchronized Temperature Monitoring: Built-in temperature sensor with a range of -40°C to 80°C, suitable for various climatic conditions.
