The RFM300+ series of refractometers is the result of a combination of excellence in design and manufacturing led by customer needs. With a wide measuring range and Peltier temperature control of the flat, easy clean prism, the RFM300+ and 300-T Series refractometers offer extremely rapid temperature stabilization of the sample.

Incorporating wide beam optics, RFM300-T Series refractometers are capable of measuring non-homogenous samples such as fruit juice with pulp, opaque chemical compounds and emulsions that are normally difficult to read with optical refractometers or those digital refractometers that do not address the need to measure “difficult samples.”
