This is the standard model irrometer used with all irrigated row, field, and tree crops. The Model R can also be used in greenhouse and nursery applications, or when monitoring the Vadoze Zone.
Standard features of this irrometer include a tough plastic body that is impervious to attack by soil chemical or electrolysis, a durable ceramic tip responsive to soil moisture variations, and a sealed gauge that indicates soil function from 0 to 100 centibars.
Gauges operate counter-clockwise. A large reservoir holds a reserve supply of water to replace water lost by the action of drying soil and there is a handy screw cap for filling the fluid reservoir. Partial unscrewing of this cap realeases air and refills the tube with water from the fluid reservoir.
All joints are permanently sealed. Irrometer fluid, supplied with the accessory Service Unit, colors the water for easy water level observation. TheModel R Irrometer requires Service Unit and Soil Coring Tool with initial order. Remove when temperature falls bellow 20°F.
