Moisture Monitoring

Description The IRROMETER Model MLT (Miniature Low Tension) tensiometer was designed for use in small containers commonly used in greenhouses and nurseries. Its compact design and short insertion depth of 4.75 inches (12 cm) allows the MLT to be installed in smaller growing vessels. With a range of 0-40 centibars (cb) or kilopascals (kPa), this instrument is for use in situations where tensions above 30 cb (kPa) are rarely expected. Gauge increments of 1 cb (kPa) provide a benefit where finer resolution near saturation is needed. This model instrument is also well suited for conditions where rapidly changing soil moisture conditions need to be observed. The "Quick-Flo" ceramic tip is colored blue for easy identification Click here for Irrometer's instruction manual.

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 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.

Description Information you can use, when you need itMeasure the soil moisture available for your plants and automatically transmit to an IrroCloud Monitor. This tensiometer measures moisture levels in centibars and gives you the same information as typical analog versions you have to see in person. You can hook up to 6 of these to every IrroCloud Monitor and see the data on your smart phone, desk computer, or laptop anywhere in the world. The user-friendly IrroCloud software lets you see the  data in many ways—graphs, averages, individual sites, rain events, and several other useful configurations, turning the data into actionable information.

Description The syringe is used for extraction of the collected sample. Connect the plastic extraction syringe to the tubing by twisting it onto the end fitting and draw up on the syringe plunger to extract the soil solution for analysis. *Between samples, it is important to rinse the syringe with distilled water to prevent carry-over contamination from sample to sample. For Installation and Operation Instructions click here.

Description A hand vacuum pump with gauge and tubing adapter is used for applying vacuum to the tube for sample collection. We recommend using the Vacuum Pump on tubes longer than 12 in. (30 cm) to apply proper vacuum. The extracted soil water samples are commonly tested with electronic meters or portable test kits. This useful in-field sampling technique is quick and easy to perform, which makes it well suited to the frequent fertigation schedules common with certain growing conditions.
