The IRROMETER Model TGA tensiometer is specifically designed for applications such as parks, golf courses, cemeteries, freeways & dividers, athletic fields, and industrial landscaping. Our Model TGA is aligned horizontally to allow for measuring irrigation in the shallow root zone of turf and landscaping, while also incorporating the IRROMETER Adjustable Moisture Level Selector & Switch feature. This feature allows for setting a desired point on the gauge at which a switch will be closed for automatic irrigation. The Adjustable Moisture Level Selector & Switch can be compared to a thermostat, continually measuring the soil moisture and signaling the controller whenever a water application is desirable, or preventing an application when there is no need for one.
