Can we help you?

The RX-7000a (alpha) is an improved (upgraded) model for a measurement range of refractive index and measurement temperature of an RX-5000a (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-7000a (alpha) has the manual calibration facility which compensate difference in standard liquids and measurement values by other refractometers
