Measure what is happening in the root zone so you can set, verify, and fine-tune irrigation with real data. Use the Blumat Digital Moisture Meter for quick soil-tension readings, Irrometer tensiometers for continuous visual monitoring at specific depths, or electronic sensors and data loggers for remote or real-time tracking. Choose the tool based on how often you want to check moisture, the depth you need to measure, and whether you need logged data.
Moisture Monitoring
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.

Voltage Irrometer 12"
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.

IRROMETER Company, Inc. IrroCloud Monitor IC-10-IR
Real-time, accurate data showing you the moisture levels at each sensor in your system - too wet, too dry, or just right! It not only gives you the here-and-now information but also has an adjustable timeline for historic and/or specific dates and times. For example, you can start with a 3-month graph and then zoom in on any day and time.Although very simple, easy to use and interpret, it still provides vital, accurate, and critical information. It even tells you how many hours and minutes your irrigation system was on as well as rain gauge information (if you get that option).The four C batteries that normally last more than 2 years power the IrroCloud which connects with up to 6 Voltage Irrometers for soil moisture readings. These sensors report directly to the IRROcloud platform without any need for additional gateways or devices. If not the most, at least one of the most simple, affordable, and reliable solutions for automatically collecting sensor data and storing it in the cloud, for quick access at any time. Since the IrroCloud doesn't require an external power source or even a solar panel, you can easily install it in even the most challenging fields and orchards.The IRROcloud web application provides an intuitive interface with a quick reference dashboard and graphing suite.

Irrometer Watermark Soil Moisture Sensor, 15'
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.

Irrometer Low Tension (LT) Model, 18"
The IRROMETER Model LT (Low Tension) tensiometer was designed to operate in coarse sandy soils and non-soil growing media. 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. Model LT IRROMETERS can be used for manual measurement and tracking of soil moisture status in coarse sandy soils and growing media. When equipped with optional electronic output and data logging equipment, measurement and tracking can be done automatically. The low tension vacuum gauge on this model can be replaced with electronic measurement options, or automatic switching devices which can activate peripheral equipment at desired soil water tension levels. See the "Automation and Output Options" specifications for more details. The Model LT is the best choice for container media such as peat, bark, sand, perlite and vermiculite. It can also be used in any soil when the moisture is being managed close to field capacity. Click here for Irrometer's instruction manual.
