- the hand-held digital refractometer
is a compact, easy-to-use refractometer for measurements in laboratory
and production environments. This instrument can be used in two ways: Either
put it on a flat surface and place a drop of sample onto the measurement
cell, or immerse the sensor directly into the fluid. As soon as you press
the measurement kay, the result is displayed in the desired units on the
high resolution LCD display. Auto temperature compensation.
