Blumat Digital Moisture Meter

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.
