Product Description:
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.
1. Type & Length Options:
LT (Low Tension, 0–40 Centibar) – Best for potting soil, peat-based potting mixes, coco coir, and living soil. This gauge is more sensitive at lower moisture tensions, offering better resolution in the wetter range—ideal for containers and grow media where consistent moisture is key.
SR (Standard Range, 0–100 Centibar) – Designed for field soils like loam and clay. Offers a broader range to monitor drier conditions over time, commonly used in on farms, and general agriculture.
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.
3. Pump Service Kit (Optional Add-On):
While not required, the Pump Service Kit is a valuable tool for setup and maintenance. It includes:
Manual vacuum pump – helps fill and prime Irrometers, draw vacuum for faster readings, and check for leaks
Green dye – improves visibility of internal water level from a distance
Setup instructions and service guide
You only need one pump kit per site, no matter how many Irrometers you're using.
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.
