This product is made in the USATurf-Tec Model R Irrometer - Tensionometer
For measuring soil moisture by using soil water tension

Turf-Tec Irrometer - Tensionometer - For measuring soil moisture by using soil water tensionThe Model R is the standard one-piece Irrometer for general use with irrigated row, tree, and field crops, but can also be used in greenhouse and nursery applications or for monitoring Vadoze Zones. Simply make a hole and insert the tensionometer into the soil, fill it with distilled water and prime the suction with the Vacuum Hand Pump (Model R Irrometer Service Kit). After about 24 hours, the ceramic block will reach equilibrium with the soil and give the moisture level. Leave it installed in the soil and you can periodically check to see when your crops or trees need additional irrigation.

Features a tough Butyrate plastic body that is impervious to soil chemicals or electrolysis, a fixed porous ceramic tip designed to give quick response to variations in soil moisture, and a hermetically sealed gauge that indicates soil suction from 0 to 100 centibars (gauge operates counter-clockwise). A large reservoir with a screw cap for filling holds a reserve supply of water to replace water lost by action of drying soil.

Partial unscrewing of cap releases air, and refills the tube from the reservoir. All joints are permanently sealed. Irrometer fluid, supplied with the Service Unit accessory, adds color to the water for easy water level observation. The Model R Irrometer requires the Service Unit accessory and the Soil Coring Tool with the initial order.

     

Hermetically Sealed Gauge
Accuracy and long life are ensured by a
hermetically sealed cover with a
molded-in diaphragm that keeps dirt and
moisture out and compensates for
variations in temperature and barometric
pressure.

Air-Free Gauge The water seal
prevents air from entering gauge, so
gauge and chamber remain full regardless
of fluid level in instrument.
 

The IRROMETER Body is constructed of
tough durable plastic impervious to attack by soil
chemicals or electrolysis.

The IRROMETER is available in standard
lengths of 6, 12, 18, 24 (15, 30, 45 & 60 cm)

Closure Large cap for easy operation and
better control. Cap removes for filling reservoir.
Submerged valve gives a positive leak proof
seal. Servicing is instantaneous with a
twist of the wrist.

Reservoir holds a reserve supply
of fluid sufficient for several irrigation
cycles under average operating
conditions. Unscrewing cap part way
releases air and fills tube to replace fluid
lost by the action of drying soil.

Ceramic to Plastic connections are
permanently leak proof.

Ceramic Tip has many times the strength of
conventional tips. It is more porous to give quick
response to variations in soil moisture.
