摘要:Diviner 2000便携式土壤水分廓线仪(简称Diviner 2000)是一种集现代高科技与智能化于一体的新型土壤水分测量仪器,由探测器(探头)、连接电缆和显示器组成。测量时将探头插入PVC管中并快速提出,即可实现测量点垂直剖面上的土壤水分廓线数据,可以在不破坏土壤结构的情况下实现长期高精度测量,测量层数最多可达16层。在监测管埋设时,要保证钻孔直径与监测管相同或略大,监测管外壁与土壤紧密接触,同时确保监测管垂直于地表。在仪器标定时,Diviner 2000测定的土壤含水率反映的是测试区内的体积含水率,而烘干法测定的是质量含水率,为了准确标定,必须进行土壤体积质量的测定。
Diviner 2000 is a new type of soil moisture measuring instrument which has both modern high-tech and intelligent in.It is made by detector,stub cable,and displayer.It makes the detector into the PVC pipe and put forward quickly,then the soil moisture contour data of the vertical section is measured.It could make long-term and high precision measurement as not destroying the soil structure,and the measurement layer could be 16 at most.Make sure that the hole diameter is slightly bigger than the monitoring tube,or the same,monitoring pipeline outer wall close contacts with the soil,monitoring tube in vertical the earth surface,when inbuilt the monitoring pipe.As in instrument standardization,Diviner 2000 determines volatile water content,but oven drying method determines quality moisture content,so in order to make an accurate standardization,the soil quality of unit volume must be measured.
