Irrometers are reliable, American-made tensiometers that provide direct readings of soil water tension, helping growers make informed irrigation decisions. These analog tools measure the effort required by plant roots to extract water, offering insights into soil moisture status without the need for electronics or calibration. Comes with a syringe to fill the tensiometers. 

1. Available in three sensor depths

• 6" – Monitors near-surface moisture

• 12" – Most popular; great for beds and large containers

• 18" – For deep-rooted plants or lower soil profile monitoring

Note: Irrometer readings are in centibar (kPa), which align with digital moisture meter readings in millibar—just shift the decimal (e.g., 100 mbar = 10 cbar).

2. Quantity Options

Order up to 4 Irrometers per kit. 

Irrometers offer a simple, field-tested way to make smarter irrigation decisions. Use one at your target depth—or stack multiple to track moisture movement through the full root zone.
