Whether for the determination of the current soil condition, the evaluation and management of irrigation processes or capturing processes in the soil: the water content of the soil is a basic parameter for many question in the agricultural sector, soil science and environmental protection.
It is a determining factor for plant growth. It influences chemical processes in the soil and thus soil formation itself, as well as the spread of nutrients or pollutants. The water content measurement allows to determine favorable and unfavorable plant locations, to detect changes in ecosystems and to make statements about important soil and water balance processes.
The standard version of the UMP-1 sensor is designed for connection to a data logger via cable, thus, a different number of sensors can be connected to one logger. The sensor measures soil moisture, temperature and conductivity. It is particularly suitable for long-term measurements.
The UMP-1 BT sensor is the wireless version of the UMP-1 sensors and opens up the market to smartphone based measurement technology. Measurement data are transmitted by Bluetooth directly to an Android smartphone. The sensor has been designed for flexible use in the field and is primarily suitable for determining instantaneous values and for short-term series of measurements on different measurement sites.
The UMP-1 BTim is the compact version of the UMP-1 BT sensor. It consists of a shaft with the integrated UMP-1 BT sensor, a height-adjustable handgrip, a smartphone holder and a spring guide for inserting the measuring rods. This device has all possible advantages to fast and easy carry out measuring campaigns with lots of single measurements, distributed over larger areas.
The UMP-1 BT Plus is the advanced version of the UMP-1 BT sensor. Data are transmitted via Bluetooth
to any windows-PC and can be visualized and managed with the application software. Additionally this sensor features an integrated data logger and can therefore be used autonomously.
The SMT-100 measures the water content and the temperature. Due to its unique measuring principle, it combines the advantages of a low-cost FDR system with the accuracy of a TDR system, resulting in reliable measuring values even in clayey soils. Its compact and robust but also elastic and thus resistant design make the SMT-100 a durable, flexible and versatilely applicable measuring instrument.
The SM150T is a capacitive soil moisture sensor. Besides the soil moisture it also measures the soil temperature. In combination with the Moisture Meter - HH150 - it is available as ThetaKit for mobile use.
The Moisture Meter HH2 is an easy to use read-out device for Delta-T moisture sensors (ML3 ThetaProbe, SM150T und WET Sensor). As an affordable Soil Moisture Kit (e.g. Theta Probe + HH2) it is designed for mobile use in the field.
The ML3 ThetaProbe is a capacitive soil moisture sensor. Besides the soil moisture it also measures the soil temperature. In combination with the Moisture Meter HH2 it is available as ThetaKit for mobile use. Besides the generic Calibrations it can also be calibrated for specific soils to improve the accuracy.
The EnviroScan continuously records the water content in a soil profile. To perform high resolution measurements, it is possible to attach about 16 sensors to one Probe at intervals of 10 cm. With additional equipment, it also determines salt and fertilizer content.
Sentek Plus "All-in-one"
The Sentek Plus system transmits data from EnviroScan and EasyAG tubular probes wirelessly using mobile communications to an Internet server. Thus, it is possible to easily retrieve the data from the office and display them in the including software.
The Easy Test FOM/mts is a mobile TDR meter designed for the simultaneous in situ measurement of the volumetric water content, of the electrical conductivity and of the temperature in the soil.
Using the Trime-T3 tubular probe, it is possible to record moisture profiles down to a depth of 3 m, in combination with the probe head Trime-T3/IPH54 even down to a depth of 50 m. The moisture is measured using the TDR-principle.
Using the Soil Salinity Sensor, it is possible to measure the salinity of subsurface pore water on a long-term basis. It operates in the suction pressure range from 0 to 15.000 hPa.
