Moisture Meters
Irrometer Coring Tool Kit
Assemble the coring tip onto the extension sections and the handle by screwing pieces together. Use as many extensions as necessary to make the tool the appropriate depth to position the sensor. Push the coring tool into the soil at the desired sensor location no more than one foot (30 cm) at a time to get to the desired depth. After each insertion of the tool, pull it back out and remove the soil core that has accumulated in the tip. Never rotate the tool counter-clockwise while it is inserted in the ground as the pieces can become unscrewed. Often it can be easier to push on the handle with your waist or knee to improve leverage. Footjacks and "backsaver" handles are available as options that can make installation easier. Once the hole has been made to the desired depth, the sensor can be inserted. Be sure the sensor is firmly seated in the bottom of the hole and backfilled making sure the fill soil is compacted similarly to the surrounding area, as a false reading could be obtained if surface water wicks down through uncompacted soil.

Blumat Digital Moisture Meter Kits
Measure soil moisture tension directly in the root zone with the Blumat Digital Moisture Meter. Designed for potting mixes, containers, raised beds, and living soil, this digital tensiometer reads in millibars (mbar) so you can compare moisture conditions, check drybacks, and verify irrigation performance with real data. New to soil moisture tension? Read our Measuring & Managing Moisture in Living Soil to learn what mbar readings mean, how soil moisture tension differs from volumetric water content (VWC), and how sensor placement affects what you measure. Available Options ＋ Meter Only — Base unit for direct soil moisture tension readings. Meter + Protective Cap — Adds protection for the electronic meter head. Meter + Protective Cap + Battery — Includes a spare CR2032 3-volt battery. Complete Kit (Meter + Cap + Battery + Coring Tool) — Includes the Blumat Coring Tool (1" wide, 11"+ long) for clean installation with minimal soil disturbance. How It Works ＋ The ceramic cone equilibrates with the surrounding soil and the meter displays soil moisture tension in millibars (mbar). Lower numbers indicate wetter conditions; the reading rises as the soil dries and water becomes harder for roots to extract. After installation, allow about 30 minutes for a useful initial reading. Full equilibration can take longer. Once the meter is conditioned, moving it between beds or containers with similar moisture levels can provide a useful comparison within several minutes. Use the meter to establish repeatable wet and dry reference points, check moisture at root depth, compare different locations in a bed, or verify and fine-tune a Blumat irrigation system. Important Notes ＋ The electronic meter head is water-resistant, not waterproof. Do not submerge it or expose it to standing water. The protective cap should not be seated directly into soil. Trapped humidity can damage the meter head. For best comparisons, pay attention to installation depth, soil contact, and location in the root zone. Reset instructions are available here.

IRROMETER Company, Inc. 1002-SSAT Vacuum Pump
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.

IRROMETER Company, Inc. DS-50CC Extraction Syringe
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.

IRROMETER Company, Inc. Irrometer 6" Low Tension (LT) Soil Solution Access Tube (SSAT)
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 Low Tension tip (blue) for sandy soils and growing media 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. For more information see Irrometer's spec sheet and instructions.
