  • Last stock! Irrometer Watermark Soil Moisture Sensor, 15'-1

    Irrometer Watermark Soil Moisture Sensor, 15'

    1 in stock

    Description Standard WATERMARK Soil Moisture Sensor. For use with all crops. To be used with WATERMARK Meter, Monitor, Voltage Adapter or a compatible device. Reads electrical resistance in 0-200 centibar (cb) and kilopascal (kPa) range. Comes standard with half inch stripped and tinned ends. 15' (4.5 m) length This sensor consists of a pair of highly corrosion resistant electrodes that are embedded within a granular matrix. A current is applied to the WATERMARK to obtain a resistance value. The WATERMARK Meter or Monitor correlates the resistance to centibars (cb) or kilopascals (kPa) of soil water tension. The WATERMARK is designed to be a permanent sensor, placed in the soil to be monitored and "read" as often as necessary with a portable or stationary device. Internally installed gypsum provides some buffering for the effect of salinity levels normally found in irrigated agricultural crops and landscapes. Click here for Irrometer's instruction manual.

  • Last stock! Irrometer Watermark Monitor with 7 sensors and 1 Temperature Sensor-1

    Irrometer Watermark Monitor with 7 sensors and 1 Temperature Sensor

    1 in stock

    Description This assortment kit is with 1 Soil Temperature Sensor, 7 WATERMARK Sensors. The WATERMARK Monitor is a Data Logger; a device that automatically records soil moisture readings. This reading history provides a vivid picture of the soil moisture profile your irrigation practices have created. The data can be evaluated to determine ways to improve irrigation scheduling for optimum results. Individual sensor readings display on the monitor and can be taken manually at any time. The in-field display allows you to make on-the-spot checks for scheduling purposes while periodic readings are automatically taken to record the performance history.
