Designed with simplicity in mind, RFM700-M Series refractometers with Brix, RI scales as standard offer digital automatic technology at a low cost.
The RFM732-M covers the full Brix range (0-100) to 1-decimal place accuracy so is perfect for measuring both low and high concentration solutions. This makes the RFM732-M a viable choice for use within the food and beverage manufacturing sector where sugar syrups for beverage start-up or confectionery products are required to be measured.
Robust 0-100 Brix refractometer. Designed with simplicity in mind, RFM700-M Series refractometers with Brix, RI scales as standard offer digital automatic technology at a low cost.
RFM700-M Series refractometers are robust, low cost, fully automatic instruments that are ideally suited to the food, sugar and beverage industries but can also be used in many other non-food applications where temperature control is not required, for example measuring sugar (°Brix) concentrations in the food processing industry.
The RFM700-M Series features 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 together with the external power supply makes the RFM732-M ideal for use in a harsh factory environment, busy Tare House or the laboratory.
Commonly, the RFM700-M series 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.
The RFM700-M facilitates Span calibration at any value using a variety of media types, as temperature compensation may be adjusted to suit the product being used. Additionally, the instruments are fitted with AG temperature compensation, allowing the use of AG Fluids without the need to use conversion table.
