Gypsum blocks use two electrodes placed into a small block of gypsum to measure soil water tension. Wires connected to the electrodes are connected to either a portable hand-held reader or a data logger. The amount of water in the soil is determined by the electrical resistance between the two electrodes within the gypsum block. More water present in the soil will reduce the resistance, while less water will increase it.
While gypsum blocks can be relatively inexpensive and easy to install compared to other types of soil sensors, they have to be replaced periodically as the gypsum disintegrates. Gypsum blocks are also more sensitive to having readings thrown off by soil with high salinity (electrical conductivity).
I want to Purchase the Gypsum Blocks from you Can you please send me the Specifications And Price for the same.

Good Evening Sir, I am Ramesh from Pioneer Engg and Sci Indus Tirupati.
Can I have the Gypsum Blocks. If So Please send me the Specifications And Price for the same.
Thankyou
With Regards.
The related picture to this post is not a Gypsum block. That is a picture of a Watermark sensor.
