The digital salt-meter, ES-421 employs a funnel-shaped sensor
section ( conductivity ), which measures the salt % of a sample (
dilute solution of soy sauce, ketchup,mayonnaise, Worcester sauce,
sqeezed juice of pickles, etc. ) very small sample needed ( 1.0ml
approx. is enough for measurement ). ... more
The RX-7000α ( alpha ) is an improved ( upgraded ) model for a measurement range of refractive index and measurement temperature of an RX-5000α ( alpha ). The thermo module for constant temperature is equipped. It is best for measuring oils and fats of high melt point, higher refractive index perfumes, organic solvents, etc. The RX-7000α ( alpha ) has the manual calibration facility which compensate difference in standard liquids and measurement values by other refractometers.
Refractive index (nD) 1.3250 to 1.7000 Brix 0.00 to 100.0% (ATC : 5 to 70°C)
