Irrometer 206 Tensiometer Model SR Manual Gauge 6in

206 Model SR Manual Gauge 6" (15cm) | Irrometer Soil Moisture Sensors

The “SR” Irrometer is the standard instrument for use in medium to heavy soils. For precise soil testing equipment that aids in field measurements, consider the M.C. Miller Analog Resistance Meter Miller 400A, which is an essential part of any comprehensive soil testing kit.

Instrument includes a threaded replaceable tip as well as reservoir, air free gauge chamber and hermetically sealed IRROMETER vacuum gauge with dual scale of centibars and kilopascals (0-100 cb [kpa] range). For complementary air measurement tools, consider the Humboldt Concrete Air Meter Kit used to measure air content of fresh mixed samples.

Product Overview

The Tensiometer is the only direct measurement system available, which means it actually reads the physical forces at work in the soil. Tensiometers act like a dummy root, allowing the soil moisture to interact with the instrument through the ceramic tip. Soil water tension outside of the instrument tries to remove the water from it, which creates a measurable tension inside the column. This tension is read with either a mechanical gauge or a transducer attached to the instrument. While this is the most accurate and proven method available, there is some maintenance required periodically to keep them full of water, and they must be removed from the field during the winter months to avoid freezing. Additionally, measuring the soil profile using a penetrometer is essential for understanding soil compaction, which is crucial for maintaining healthy root growth and water retention.

• IRROMETER measures soil water tension which indicates plant water availability.

• The IRROMETER Tensiometer is the standard in accurate soil moisture measurement, offering growers a proven, affordable and reliable means of measuring soil moisture for irrigation scheduling.

• Accurate field data from the IRROMETER allows growers to schedule irrigation efficiently, resulting in better resource conservation and improved crop yields.* An IRROMETER will measure the actual soil water tension which indicates the effort required by roots to extract water from the soil.

• Growers and researchers need accurate field data to make informed irrigation decisions and the IRROMETER provides that information.

• Because the IRROMETER is a true measurement of soil water potential the instrument is not affected by salinity and does not require site calibration.

• The IRROMETER is available in several models with standard lengths of 6”, 12”, 18”, 24”, 36” or 48” depending on the rooting depth of the specific crop.
