Description
Irrometer sensors come made for soil (outside, gardens and farms) and for planting and potting mixes (indoor, greenhouses, and outside beds). This one - best for using with potting mixes - includes two sensors and the parts needed to set it up: a hand vacuum pump, a bottle of Irrometer fluid, 25 monthly chart forms, and a reference book. After setting up the sensors, you can use the pump to remove air from them to ensure maximum sensitivity and accuracy.
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.

Description
OPERATING PRINCIPLE: The IRROMETER operates on the tensiometer principle, which measures soil water tension. Soil water tension is the energy (vacuum) applied to soil by the plant as it draws in water for nutrition. This force is measured in centibars (cb) or kilopascals (kPa) of tension with a high reading indicating the dry end of the scale and a low reading indicating the wet end of the scale. The IRROMETER instrument consists of a sealed, fluid filled tube that is equipped with a porous ceramic tip and a special vacuum gauge.
They are installed in the ground with the tips placed at desired root zone depths. As the soil dries (increasing tension), fluid is drawn out of the instrument. This reduces the fluid volume in the IRROMETER, thus creating a partial vacuum which is registered on the gauge. The drier the soil, the higher the gauge reading. An irrigation application or rainfall event reverses this action. As water flows back into the soil (and the IRROMETER), tension is relieved in the soil and the instrument, resulting in a lower gauge reading (lower tension). In effect, the instrument is indicating how hard the roots are working.
Due to the IRROMETER’s unique principle of operation, no calibrations are necessary under normal operating conditions for different soil types. A gauge reading of 50 cb (kPa) indicates that the roots are extracting the same amount of moisture whether the crop is planted in sandy soil or clay soil.

Irrometer sensors come made for soil (outside, gardens and farms) and for planting and potting mixes (indoor, greenhouses, and outside beds). This one - best for using with potting mixes - includes eight sensors and the parts needed to set it up: a hand vacuum pump, a bottle of Irrometer fluid, 25 monthly chart forms, and a reference book. After setting up the sensors, you can use the pump to remove air from them to ensure maximum sensitivity and accuracy.
Description
Fast shallow-soil information when you need itLike the 12" version, this 6" sensor measures soil moisture and transmits it to an IrroCloud Monitor. Because this one is closer to the soil surface, it works best for plants with shallow roots and for large plants when they're still small. Hook up 1-6 of these for every IrroCloud Monitor you have or plan to get and automatically have all this critical information on your phone or computer. You can also install a combination of 6" and 12" sensors on the same system with the same simple software, accuracy, graphs, averages, and configurations.
Description
SSAT (Soil Solution Access Tubes), or Suction Lysimeters, were developed to easily extract soil water samples for testing. They provide the user with an accurate method of determining salinity or plant nutrient levels. Because the sample is collected at root zone depth, it reflects the true impact fertilization has on the plant material. Understanding soil water conditions helps the user make informed fertigation scheduling decisions resulting in improved yield and reduced fertilizer, water, labor and energy costs. Features:
Easy to install and use
Standard ceramic tip (white) for most soil types
Optional Double Suction line for longer tubes
Collects soil water sample at the root zone Crop consultants, irrigation professionals and researchers find the SSAT particularly useful because of its ability to easily gather soil water samples for testing. Commercial growers see the value of soil water sampling at the root zone because it reflects the net "effect" that fertilization has as it interacts with previously applied nutrients in the soil. Scientists also use this equipment when identifying and researching environmental contaminants and their movement in soil. Click here for Irrometer's instruction manual.

Description
The IRROMETER was first developed in 1951 to help growers improve irrigation efficiency. It provides the user with accurate information on soil moisture status regardless of soil type. The instrument measures in centibars (cb) or kilopascals (kPa) of soil water tension. This value represents the energy a plant's root system uses to draw water from the soil. Understanding soil moisture activity helps the user make informed irrigation scheduling decisions resulting in improved yield and quality while reducing water, fertilizer, labor and energy costs.

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.
