\nThe original \u201cIRROMETER\u201d instrument was the first commercially viable Tensiometer available, and is still the standard by which other methods are tested. Our IRROMETER instruments provide a direct measurement of soil water tension, which is the tension all root systems must overcome to extract water from the surrounding soil. Simple, reliable, and accurate, the IRROMETER is still the choice of many successful growers and consultants.
\nOur next option for soil moisture measurement is the WATERMARK sensor. This Granular Matrix Sensor (GMS) offers low cost, accurate readings, and easy integration with electronic reading equipment. First introduced in 1979, the WATERMARK sensor has grown in popularity and gained acceptance worldwide for reliability and accuracy in measuring soil moisture. For over two decades, the WATERMARK sensor has been utilized in numerous research studies around the world.

\nIn use since 1978, the patented WATERMARK sensor is a solid state electrical resistance sensing device that is used to measure soil water tension. As the tension changes with water content the resistance changes as well. That resistance can be measured using the WATERMARK Sensor.
\nThe sensor consists of a pair of highly corrosion resistant electrodes that are imbedded within a granular matrix. A current is applied to the WATERMARK to obtain a resistance value. The WATERMARK Meter or WATERMARK Monitor correlates the resistance to Centibars (kilopascals) of soil water tension.
\nThe WATERMARK is designed to be a permanent sensor, placed in the soil to be monitored and \u201cread\u201d as often as necessary with a portable or stationary device. Internally installed gypsum provides some buffering for the effect of salinity levels normally found in irrigated agricultural crops and landscapes.

<\/a>The original \"IRROMETER\" instrument was the first commercially viable Tensiometer available, and is still the standard by which other methods are tested. Our IRROMETER instruments provide a direct measurement of soil water tension, which is the tension all root systems must overcome to extract water from the surrounding soil. Simple, reliable, and accurate, the IRROMETER is still the choice of many successful growers and consultants.<\/p>Our next option for soil moisture measurement is the WATERMARK sensor. This Granular Matrix Sensor (GMS) offers low cost, accurate readings, and easy integration with electronic reading equipment. First introduced in 1979, the WATERMARK sensor has grown in popularity and gained acceptance worldwide for reliability and accuracy in measuring soil moisture. For over two decades, the WATERMARK sensor has been utilized in numerous research studies around the world.<\/p>

Irrometer Tensiometers<\/span><\/h3>
\u00a0<\/p>
The IRROMETER Tensiometer is the standard in accurate soil moisture measurement, offering growers an inexpensive and reliable means of measuring soil moisture for irrigation scheduling. An IRROMETER will measure the actual soil water tension, which indicates the effort required by root systems to extract water from the soil. Because the IRROMETER is a true measurement of soil water potential, the instrument is not affected by salinity and does not require site calibration.<\/p>
The IRROMETER is available in several models, with standard lengths of 6\", 12\", 18\", 24\", 36\", or 48\" dependent on the rooting depth of the specific crop. Longer lengths are available by request.<\/p>

Watermark Sensors<\/span><\/h3>
In use since 1978, the patented WATERMARK sensor is a solid state electrical resistance sensing d\nevice that is used to measure soil water tension. As the tension changes with water content the resistance changes as well. That resistance can be measured using the WATERMARK Sensor.<\/p>
The sensor consists of a pair of highly corrosion resistant electrodes that are imbedded within a granular matrix. A current is applied to the WATERMARK to obtain a resistance value. The WATERMARK Meter or WATERMARK Monitor correlates the resistance to Centibars (kilopascals) of soil water tension.<\/p>
The WATERMARK is designed to be a permanent sensor, placed in the soil to be monitored and \u201cread\u201d as often as necessary with a portable or stationary device. Internally installed gypsum provides some buffering for the effect of salinity levels normally found in irrigated agricultural crops and landscapes.<\/p>
