Delta T - SM 150T – Accurate measurement of soil moisture regardless of soil type

Do you want to know when to water your crops?

You cannot afford the risk of leaving too much or too less moisture in your fields. Inefficient irrigation management can lead to sub-optimal yields.

By knowing the soil moisture and temperature readings in your fields, you can know the right amount of water your crops need and schedule irrigation accordingly to gain optimal yields. Precise irrigation scheduling can also help reduce water, fertilizer, labor and energy costs.

How does Delta T - SM 150T soil moisture sensor work?

Delta T is easy to install and comes with a built‐in temperature sensor to give super-accurate data used by researchers and growers all over the world. It is an ideal soil moisture sensor for both soilless and soil applications in greenhouse and open field.

The soil moisture output signal is a differential analog DC voltage that is converted to soil moisture by a data logger or meter using the supplied general soil calibration. The soil moisture content can also be calibrated for specific soils. Fully integrated with NetBeat™, the first irrigation system with a brain, the sealed plastic body is attached to two sensing rods directly inserted in the soil to enable highly accurate readings.

What makes Delta T the ideal choice for monitoring soil moisture?

Powered by Netbeat™, Delta T gives research grade accurate measurement of soil moisture and temperature reading in real-time ‐ essential for critical control and irrigation decisions.
