			==Means of Testing DEF==
			*Your main thing is measuring the concentration of Urea in the (Aqueous) Water Solution

			===Refractometer===
			*There are specialized [[Refractometers]] for testing DEF
			*These will be covered on [[DEF Refractometers]]

			===Buoancy Based Systems===
			*These are similar in form to those [[Battery Acid Testers]]
			*Essentially a Dropper (or more rarely a cup) with beads or disks etc inside it that float to marks in a gauge on the side depending on the parameters of the liquid
