The hydraulic characteristics of two trickle irrigation emitters, type micro-sprinkler Carborundum, model MSIII, were evaluated by analyzing the manufacturing variation coefficient and pressure discharge relationship. According to the ASAE classification, in relation to the manufacturing variation coefficient, the evaluated micro-sprinkler are considered as average. With the data obtained from the discharge versus pressure, the characteristic equation of each micro-sprinkler was found. The one with light green socket presented an equation q = 6.9235H0.3804, with a determination coefficient (R2) equal to 0.98 and flow regime considered completely turbulent. The one with pink socket presented an equation q=28.78H0.0853, with R2 equal to 0.80 and, according to the exponent discharge value, it is considered as self-compensating. About the hysteresis phenomenon, its amplitude was considered negligible.
