Indigeneous Tensiometer

Description

Tensiometers directly measure Soil Suction – the force that plants have to overcome to get needed water, the force that determines which way moisture will move in the soil. Consisting of a tube with a porous ceramic tip at the bottom, a vacuum gauge, and a sealing cap, the Tensiometer is first filled with water and inserted into the soil. It registers the vacuum created when water drains out; therefore, as the soil dries out, the vacuum gauge dial moves. The reverse happens when there is excess moisture in the soil. By a process of osmosis water enters the Tensiometer, lowering the vacuum. lt shows on the gauge as decreasing Soil Moisture Tension. When the moisture in the soil attains saturation, the pointer in the vacuum gauge will show zero.

Durable and dependable, these Tensiometers offer a host of advantages compared to other methods of measurement of soil moisture:-

• Direct, continuous measurements
• Much greater precision
• Less cumbersome
• For all types of soil conditions
• No calibration required
• No power source required, or electrical leads 
• Portable, with simple field-replaceable parts

The standard model is designed for permanent installations and is constructed of corrosion, heat, and chemical resistant plastic for long life. The sealed gage is protected from outside dust and moisture and uses a water seal to keep the gage air free for better sensitivity. The durable ceramic tip resists breakage and is replaceable for longer instrument life.

A reservoir holds a reserve supply of water to reduce maintenance and uses a rubber stopper to positively seal the internal chamber. Unscrewing the lid loosens the stopper to replace lost water from the reservoir and releases excess air.

The Tensiometer comes with a bottle of tensiometers fluid to color water for easier service. The optional soil coring tool assures proper installation and function by providing the proper hole diameter.

Tensiometer Priming Syringe is required to remove air from tensiometers before installation. A single syringe unit can be used with any number of tensiometers. 

Available in various Sizes: 15, 30, 45, 60, 90 & 120cm
