The RFM742 is a 2-decimal place instrument ideal for use in beverage plants. This refractometer has robust construction a sapphire prism mounted in an easy clean stainless-steel dish and an outer casing that is sealed and shaped to withstand sample spillage and moisture ingress. This combined with the external power Supply makes the RFM742 refractometer ideal for harsh factory environments or busy laboratories. It includes ATC and comes with a keypad.

The RFM742 refractometers are supplied to operate in the °Brix scale with results temperature compensated to 20°C in accordance with ICUMSA. Additional user scales provide measurement in different formats such as various wine Refractive Index (RI) & FSII as well as allowing custom scales to be loaded in accordance with product data.
