Irrometer Kits
Description Get constant, at-a-glance readings of soil moisture with the original American-made tensiometer. Irrometers have been trusted by growers for decades to show how hard plant roots are working to access water. Analog and always ready, they provide clear insight into your soil without electronics or calibration. Use one at your target depth, or stack multiple to track moisture movement through the full root zone. Available Options Irrometers come in two versions: For Potting Soil (LT, 0–40 cbar) — available in 6″, 12″, and 18″ lengths. For Native Soil (SR, 0–100 cbar) — also available in 6″, 12″, and 18″ lengths. Note: Irrometer readings are in centibar (cbar). To compare with Digital Moisture Meter readings in millibar (mbar), just move the decimal (100 mbar = 10 cbar). Service Kit Options Choose the setup that fits your needs. Service kits improve setup and speed up readings by letting you pull a vacuum inside the Irrometer. This removes trapped air, helps check for leaks, and makes the instrument respond more quickly. Both kits also include Irrometer fluid/dye (for visibility) and instructions. Basic Service Kit — syringe, fluid/dye, instructions (simple way to pull a vacuum) Pump Service Kit — hand pump, fluid/dye, instructions (faster way to pull a vacuum and check for leaks) None — Irrometer only

Irrometer Miniature Low Tension (MLT) Model
The IRROMETER Model MLT (Miniature Low Tension) tensiometer was designed for use in small containers commonly used in greenhouses and nurseries. Its compact design and short insertion depth of 4.75 inches (12 cm) allows the MLT to be installed in smaller growing vessels. 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 Click here for Irrometer's instruction manual.
