Application
The refractometer is a portable, precision, optical
instrument used for measuring Diesel Exhaust Fluid
(DEF) concentration.
When a liquid sample is placed on the prism, the light
passing through it is bent. The more concentrated the
liquid, the more the light will bend. The refractometer
contains a reticle, or scale, that is enlarged through the
eyepiece to measure this light.
The values on the scale have been established to
evaluate the DEF condition.
The scale without any
liquid on the prism.
The scale with liquid
on the prism.
The reading is taken at
the point the shadow line
crosses the scale.
