DX 721 - Digital wide range soil moisture probe

The DX 721 is a state-of-the-art soil moisture probe – suitable for fast measurements in changing locations or
for long term monitoring in fixed locations.

The DX 721 are optimized and calibrated for use in typical agricultural soils.

The accuracy depends on the application.

With the standard calibration up to ± 3% (VWC) in mineral soils with medium salinity from 0 to 50% VWC
can be achieved.

With soil-specific calibration, accuracy of up to ± 1% (VWC) can be achieved.

Measurement is also possible in other materials, for example: mineral wool, coconut fiber, wood fiber, paper.

The display values must then be interpreted/calibrated for the specific material.

DX 721 sensors are interchangeable -the sensors are fully calibrated.

Simply “plug in and measure”!

With the suitable PROD01 / PRO D05 meters this is a reliable reference for agricultural/horticultural
applications.

The multichannel data logger meters PROD05.2/.3 can combine up to 3 probes in one instrument
– or combine the probes with each of the available DX-digital probe to incorporate a multiparameter
measuring solution “in one hand”.
