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 & 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
deter mine the concentration of test reagent solutions. and cali
bration line (Wt) for instrument control.
REF-414, Hand Refractometer, Measuring The Freezing Point
It permits measuring the freezing point of glycol ethylene and propyl
ene solutions. Especially suitable for controlling lead battery charges &
concentration 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 & 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
polarizer filter.
