    Blumat Digital Moisture Meter

    Description Description This professional moisture meter will show you how dry or wet the soil is at the push of a button. The digital moisture meter can be an ideal tool to help when dialing in your Blumat or other garden irrigation system. Keeping your soil at the ideal moisture level keeps microbes and other microorganism populations happy. *DO NOT GET ELECTRIC/DIGITAL PART OF METER WET. USE PROTECTIVE CAP, ESPECIALLY IF YOU ARE USING THESE OUTSIDE, HAND-WATERING, OR FREQUENTLY APPLY FOLIAR SPRAYS. How it Works The ceramic extension is soaked in and filled with water, just like a Blumat sensor. When this is inserted into the growing medium, the medium exerts a pressure on the water inside the cone. When the medium is more dry, it pulls harder on the water inside the cone. When the medium is more moist, the force pulling inside the cone is less. These forces of pressure correlate to different readings on the meter. A reading of 0 indicates standard water, while a high reading of 750 or so indicates sawdust completely void of moisture. The digital moisture meter is a tensiometer, but indicates moisture levels using pressure as a correlative. Reset Your Meter! When you first get your Digital Moisture Meter, it is best practice to reset it. It's also advisable to reset it periodically with continuous use. Click here for instructions.

Yes Comparison Chart Blumat Digital Moisture Meter Analog Moisture Meter 12" Low Tension Irrometer Measures Moisture in mBar hPa, hPa = mBar kPa, kPa = 10 x mBar Accurate Readings in About 45 minutes to an hour As little as 5-10 minutes Almost instant Can Get Wet No Yes Yes Needs a Battery Yes. Can be replaced: IG16246 No No Needs a Service Kit No No Yes. One sevice kit can service multiple irrometers: IG17954 Additional Info Additional Info Wait until after watering media to let the moisture evenly disperse and stabilize before trusting readings from the meter. Aim for 100mbar on average in living soil. Some gardeners report best results at 40mbar–I personally get overwatering symptoms there. Let mbar readings on your meter be a guide to plant health, not a tyranny that rules your mental peace. The meter cannot be used in extremely airy or chunky media such as chunky perlite, lava rock, etc. When the ceramic is in contact with air, the pressure readings will be extremely high. However, your plant roots may have access to moisture in these media even when the meter is displaying high readings. Avoid getting the digital display wet. The protective cap is highly encouraged in all circumstances, and is completely necessary for outdoor growers as well as those who supplement with any over-the-top watering. Do not drop or otherwise rattle the display. Keep the digital display in dry storage when it’s not in use. Guide to Blumat Digital Moisture Meter | Irrigation Equipment

  • Irrometer Low Tension (LT) Model, 12"-1

    Irrometer Low Tension (LT) Model, 12"

    Out of stock

    Description 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.

  • Irrometer Pump Service Kit-1

    Irrometer Pump Service Kit

    Out of stock

    Description Service Units are designed to aid users in the placement and installation, interpretation of readings, and maintenance of IRROMETER soil moisture indicators. Several helpful items are included in the kit. The primary component of a Service Unit is a small hand vacuum pump. The pump is designed to seal on the reservoir portion of the instrument body and is used to create a vacuum manually, evacuating any air contained in the tensiometer. These instruments function with the greatest accuracy when all air has been removed. One Service Unit will service multiple instruments. The Pump Service Unit is different in that it includes a pump with an integral vacuum gauge that registers in centibars (cb) or kilopascals (kPa). This is used to validate accuracy of the gauge on the IRROMETER being serviced. Click here for Irrometer's instruction manual.
