Watermark monitor. Complete set for automatic logging of soil moisture data, consisting of datalogger, 7 Watermark sensor (5x with 6 m cable and 2x with 10 m cable), temperature sensor, software and RS232 communication cable. Inclusive quick connectors and pvc installation pipe. ...
Manufactured by:MMM Tech Support GmbH & Co. KG based inBerlin, GERMANY
The Watermark Sensor is a robust, user-friendly sensor, maintenance free, frost proof and buffered against varying salt contents of soil solution. The cable can be spliced up to a total length of 100m. However its reaction time to soil moisture variations is somewhat slower than tensiometer or volumetric sensors. Interpretation of data is easy, since measurement result is given in Centibar (soil ...
Manufactured by:Irrometer Company, Inc. based inRiverside, CALIFORNIA (USA)
Handheld meter for reading 200SS WATERMARK sensors. Adjustable for soil temperature variations. Touchpad operating panel with LCD ...
Manufactured by:Irrometer Company, Inc. based inRiverside, CALIFORNIA (USA)
In use since 1978, the patented WATERMARK sensor is a granular matrix sensor used to measure soil water tension. Water in the soil exchanges with the proprietary matrix inside of the sensor, creating a relationship between measured resistance and soil water tension. The sensor consists of corrosion resistant electrodes imbedded within a granular matrix, contained in a perforated stainless-steel ...
Manufactured by:Spectrum Technologies, Inc based inAurora, ILLINOIS (USA)
Measures soil moisture tension from 0 to 200 centibars. The Watermark Soil Moisture Sensors is an established method of tracking soil moisture trends in crops, vineyards, or other areas where moisture level is a concern. Place sensors in the upper and lower thresholds of the root zone, in turf, or in other growing media. Reads moisture from 0 (saturated) to 200 (dry) ...

The WATERMARK Monitor is our stand-alone data logger, providing users with a reliable, simple, and effective means of collecting information in the field. As well as recording data, the display on the Monitor and can be used to view readings at any time for spot checking conditions. The Monitor records soil moisture, soil temperature, irrigation on/off status, and rain gauge counts for an ...
Manufactured by:M.W. Watermark LLC based inHolland, MICHIGAN (USA)
AFPCS is used in conjunction with air-operated diaphragm (AOD) feed pumps to automatically increase the feed pump pressure during the filtration cycle. High initial feed pump pressures can build a very tightly packed, impermeable layer of solids on the filter cloth, restricting the flow of slurry and ultimately the density of the cake. Reduced initial feed pressure allows a soft layer of slurry ...

Soil moisture sensors that measure the moisture tension in the soil are read out with the soil moisture meter Watermark. The measuring principle is similar to that of the gypsum block system. The special sensors however do not dissolve in the soil and have a more consistent distribution of pores so that more accurate measurements are ...
