A fluid dispenser for dispensing a fluid, the fluid dispenser comprising: a main body, the main body defining a fluid reservoir for containing the fluid; a measuring reservoir; an output nozzle for selectively dispensing sa id fluid contained in said measuring reservoir; a valve in fluid communication with t he fluid reservoir, the measuring reservoir and the output nozzle, the valve being configurable between a measuring configuration in which the fluid and measuring reservoirs are in fluid communication with each other and a dispensing configuration in which the measuring reservoir and the output nozzle are in fluid communication with each other; a piston mounted inside the measuring reservo ir for reciprocating movement relative thereto between a piston first position and a piston second position, the piston substantially sealingly engaging the measuring reservoir; a piston actuator operatively coupled to the piston for moving th e piston relative to the measuring reservoir between the piston first and second positions, the piston actuator including an actuating arm pivotally mounted to the main body so as to be pivotable between an arm first position and an arm second position, the actuating arm being operatively coupled to the piston such that when the actuating arm is in the arm first position, the piston is in the piston firs t position, and when the actuating arm is in the arm second position, the piston is in t he piston second position; and a valve actuator for selectively configuring the valve between the dispensing and measuring configurations.
