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 tensiometers measure soil water tension, also called soil moisture tension: how hard plant roots have to work to extract water from the soil. The analog gauge provides a continuous, at-a-glance reading without electronics, making it useful for monitoring irrigation and comparing moisture conditions at different depths in the root zone.

Want to understand the readings? See our Measuring & Managing Moisture in Living Soil for a deeper explanation of soil moisture tension, mbar/cbar/kPa, sensor placement, volumetric water content (VWC), and using moisture measurements to manage irrigation.

Available Options +

Choose the model for the soil or growing media you are measuring, then select the length for the depth you want to monitor.

  • Low Tension (LT), 0–40 cbar — for potting mixes, living soil, containers, raised beds, and other relatively wet or coarse growing media. Available in 6″, 12″, and 18″ lengths.
  • Standard (SR), 0–100 cbar — for native and field soils where a wider tension range is useful. Available in 6″, 12″, and 18″ lengths.
How It Works +

The water-filled Irrometer exchanges moisture through its ceramic tip until it comes into equilibrium with the surrounding soil. As the soil dries, tension inside the instrument increases and the gauge reading rises. After irrigation, the reading falls as the soil becomes wetter.

Irrometer gauges read in centibars (cbar). Soil water tension can also be expressed in kilopascals (kPa) or millibars (mbar): 1 cbar = 1 kPa = 10 mbar.

Choosing a Length +

Length determines the depth of the ceramic tip and therefore the part of the soil profile you are measuring. A 6″ Irrometer monitors closer to the surface, 12″ reaches farther into the root zone, and 18″ is useful in deeper beds or when you want to track moisture movement lower in the soil profile.

Using Irrometers at more than one depth can show how deeply an irrigation event recharged the root zone instead of relying on a single measurement near the surface.

Service Kit Options +

Service kits make setup and maintenance easier by helping pull a vacuum inside the Irrometer. This removes trapped air, helps identify leaks, and speeds instrument response. Both service-kit options include Irrometer fluid/dye and instructions.

  • Basic Service Kit — syringe, fluid/dye, and instructions for a simple way to pull a vacuum.
  • Pump Service Kit — hand pump, fluid/dye, and instructions for faster vacuum service and leak checking.
  • None — Irrometer only.
Important Notes +
  • Irrometers must be filled and free of trapped air to respond properly.
  • Good contact between the ceramic tip and the surrounding soil is important for a representative reading.
  • Instrument length affects both measurement depth and the analog reading, so compare readings with the Irrometer length in mind.
  • One service kit can be used to maintain multiple Irrometers.
