What is an IRROMETER? When? Where? and How Much? Is the soil too wet... or too dry? These are critical questions growers must ask themselves when scheduling irrigation. In recent years, other issues such as water availability and environmental concerns, as well as pest and disease mitigation concerns have brought additional burdens to scheduling decisions. There are many ways to answer these questions, some complicated and expensive, some simple and affordable. White there are several methods to measure soil moisture status, many growers, scientists and irrigation consultants prefer the...

Closure - Large cap for easy operation and better control. Removes for filling reservoir. Submerged valve gives a positive leak-proof seal. Hermetically Sealed Gauge -Accuracy and long life are ensured by a hermetically sealed neoprene cover. The molded-in diaphragm keeps dirt and moisture out and compensates for variations in temperature and barometric pressure. Air-Free Gauge Chamber -The water seal prevents air from entering gauge, so gauge and chamber remain full regardless of fluid level in instrument. Reservoir - Holds a reserve supply of fluid sufficient for several irrigation cycles...

Irrigation Scheduling with the IRROMETER IRROMETER instruments measure soil moisture status in centibars (cb) and kilopascals (kPa) of soil water tension, This value represents the energy a plant’s root system uses to draw water from the soil. The key element in proper soil moisture is the operator. Taking the time to interpret your sensor readings will give you a vivid picture of what is happening with the soil moisture in the root system of your crop. Usually 2-3 readings between irrigations are sufficient. Charting your readings will show you exactly how quickly (or slowly) your soil...

Service Units To achieve consistent and accurate readings, entrapped air must be removed from the IRROMETER instrument during initial installation and periodically during use. Our Service Unit kits include a hand vacuum pump used to evacuate air from the instrument. Every operator of an IRROMETER should have at least one Service Unit available (only one is needed for multiple instruments). The Standard Service Unit (#1001) works for most applications, while the optional Test Pump Service Unit (#1002) includes a test gauge on the vacuum pump for validating instrument accuracy. Kits include...
