CG‑19 Soil pH Sensor | Precisely Detect Soil Acidity & Alkalinity, Empower Smart Farming
Soil pH is critical to crop growth. Excessively acidic or alkaline soil will hinder nutrient uptake and reduce land productivity. The CG‑19 soil pH sensor is specially developed for soil‑environment monitoring. Equipped with high‑precision sensing technology, it delivers stable and reliable acidity‑alkalinity data support for agricultural cultivation, ecological research and environmental monitoring.
Core Performance for Accurate & Stable Measurement
- Wide Measuring Range & High Precision: Measuring range: 0‑14 pH; accuracy: ±0.1 pH. With fine resolution, it captures subtle pH variations in acidic red soil, alkaline saline‑alkali land and other soil types, producing readings that truly reflect actual soil conditions.
- Industrial‑Grade Sensing Probe: Built‑in special‑formula pH glass electrode resists interference from soil impurities and features fast response. It maintains stable signals and minimizes drift errors when buried long‑term in soil, making it ideal for long‑term field monitoring.
- Multiple Signal Output Options: Supports 4‑20 mA current, 0.4‑2 V voltage and RS485 (MODBUS‑RTU) outputs. It can seamlessly connect with PLCs, IoT gateways and agricultural monitoring systems for easy integration into various industrial‑control scenarios.
- Wide‑Voltage Power Compatibility: 12‑24 V DC for current‑output models; 5‑24 V DC for voltage‑output and RS485 models. Its low‑power design enables solar‑powered operation for non‑grid fields to achieve long‑term, uninterrupted monitoring.
Robust Construction for Harsh Environments
The sensor housing features waterproof and anti‑corrosion treatment, while the junction box is hermetically sealed. The probe resists soil corrosion, moisture and contamination, and the cable is tension‑resistant. It can be buried directly in soil and deployed outdoors long‑term, resisting rain, humidity, sediment and other tough field conditions to cut maintenance costs.
Versatile Application Scenarios
It is widely used in smart agricultural irrigation, field crop planting, floriculture & gardening, pastures, soil moisture monitoring, plant cultivation, scientific research, aquaculture, water‑quality pH testing and more. It delivers dependable monitoring performance across farms, laboratories, ecological‑monitoring stations and industrial water‑treatment projects.
Must‑have Device for Smart Agriculture
Eliminate the delays and hassle of traditional manual soil sampling and laboratory testing. Real‑time online soil pH monitoring allows growers to adjust fertilization schedules and remediate soil precisely based on pH data. This optimizes crop‑growing conditions, improves land utilization and crop yields, and accelerates the refined and digital transformation of agriculture.
