REF-311, Hand Refractometer, 0-12g/dl Proteins & Urine
This high-precision and widely-used model has been designed to quickly
determine the proteins in blood serum and the specific weight of urine;
indispensable for all chemical-clinical test laboratories
REF-312, Hand Refractometer, 0-12g/dl Proteins & Urine
Widely used in chemical-clinical test laboratories to determine the proteins in
blood serum and the specific weight of urine.
The instrument also features refraction index scale (Nd). to determine the
concentration of test reagent solutions. and calibration line (Wt) for
instrument control.
REF-414, Hand Refractometer, Measuring The Freezing Point
It permits measuring the freezing point of glycol ethylene and propylene
solutions. Especially suitable for controlling lead battery charges & concen
tration of heat exchange liquid in cooling systems.

REF-513, Hand Refractometer, Alcohol
It permits measuring the approximate value of the amount of alcohol in aqueous
solutions and the sugar content of grape juice. The scale directly shows
measurement results.
REF-711, Hand Refractometer, 0-26% Babo
Manual instrument indispensable for all grape growers and wine-making
industries. It features 3 measurement scales (Brix, Babo, Oechsle), for
the quick sight determination of the sugar content of grapes and musts.
REF-601A, Hand Refractometer, Gemology
Used to measure the refraction index in gemology. It features inner
protection for the light, to obtain enough lighting for measuring, and polariser
filter.
