土壤水势计特征：
- 优质陶瓷头：陶瓷头是仪器的传感部分，具有许多小孔。仪器的灵敏度取决于陶瓷头的透水（渗流）速度。具有透水快、灵敏度高、基本电位值误差小等优点。
- 智能芯片：土壤水势传感器采用低功耗MCU优质运算放大器，保证传感器低功耗、高灵敏度、信号传输稳定等功能。
- 真空压力表，侧面灌溉口，人性化设计，方便查看张力计中的水量，及时补充水分。
- 土壤水势计采用标准的 Modbus-RTU485 通讯方式，最远通讯为 2000 米。
- 支持 12-24V 宽电压充电。
应用：
土壤水势计广泛应用于科学实验、节水灌溉、温室、花卉蔬菜、草地和牧场土壤的快速测量、植物栽培、粮食储存以及各种颗粒物的含水率和温度的测量。

Attention:
Essentials of sand installation
The sandy soil installation is the same as the loam standard installation procedure. It should be noted that sufficient water must be prepared, not less than 5L. before grouting, pour water into the hole and wet the entire hole wall until there is excess at the bottom of the hole Until the water appears. Then follow the steps to slowly pour the mud into the hole, about half of the hole. The rest of the installation steps can refer to the installation of loam.
Clay installation points
Installation of the clay After drilling the hole to collect the soil, after cleaning up the impurities, soak the clay in water for more than 4 hours to soften the clay and make it easier to live into a more uniform slurry. After the soaking is complete, stir it into a vicious shape, and just grout. The rest of the installation steps can refer to the installation of loam.
FAQs
1.How to choose the installation location?
1. Install the multi-depth soil sensor after the crop is sowed
2. The installation location needs to be flat
3. Under the condition of full irrigation, preferentially select the area with less water as the monitoring location, under the condition of partial irrigation, select the humid area as the monitoring location
4. Select a position where crop growth is balanced and can represent the growth of most crops
5. To understand the root distribution of the monitored crop, generally choose a location closer to the water-absorbing root system of the crop.
Note: The installation site of the equipment should be selected at a relatively high terrain to prevent rainwater from pouring into the equipment and causing short circuits or line failures.
