Vacuum Table-subpressure-type Soil hygrometer  /Soil moisture tensiometer
M306286

It can bemeasured any point  of soil moisture situation
It is simple , easy maintenance and reliable for irrigation management 。

With  low maintenance ,it can be used for many years. NO instrument calibration and nulling need. You  just read the data in the fields and records regularly. For example, 2-3 times per week, and then drawn into a curve of soil moisture changes. Test results should be combined with  water requirement of different crop that you get from the agricultural sector , so that irrigator can estimate the next irrigation cycle of  water demand, as well asa few days ahead to prepare。

The system has the following advantages: low-cost test tube. This means that more observation points can be set up  and easy to replace and add. Stainless Steel Direct Reading Instrument can be used for the detection tube readings of  tonometers, intuitive, fast and accurate. The use of weather resistance Polycarbosilane Probe ester, high strength and it can be used a long time 。The parts can be easy to replace the maintenance.

Standard length of detection tube : 15,30,45,60,90,120 cm (depth) to meet the requirements of the majority 。 Specific length can be done according to user requirements. Application for all agricultural research and production: grassland, pasture, crops, orchards, vineyards and so on.
