Center for Irrigation Technology
Drip Emitter/Microsprinkler Index
To help increase irrigation efficiency!
The Center for Irrigation Technology (CIT) routinely tests drip emitters and microsprinklers. The following index represents all current test reports on file. Copies of these reports are available from the center (for a nominal fee to cover copying, postage, and handling).
These pages are an index of available data only. Complete test data for all emitters and microsprinklers is available in book form.
In providing results on any product tested, neither CIT nor California State University, Fresno endorses that product or implies preference over similar products not listed. Contact the center at (559) 278-2066 for further details.
CIT performs three types of tests on drip emitters and microsprinklers as follows:
For all three types of tests, the Coefficient of Uniformity (CU), Emission Uniformity (EU), and Manufacturers Variability (Cv) are calculated for each pressure tested.
- Discharge vs. Pressure - The emitters are tested over a range of pressures. Normally 25 emitters are tested.
- Discharge vs. Temperature - The emitters are tested at a single pressure over a range of temperatures. Normally 25 emitters are tested.
- Coefficient of Manufacturers Variability - The emitters are tested at a single pressure. Normally 100 emitters are tested.
