Bellingham + Stanley Digital Refractometer RFM712-M with ATC and Keypad
Designed with simplicity in mind, RFM700-M Series refractometers with Brix, RI scales as standard offer digital automatic technology at a low cost.
This refractometer, the RFM712-M, covers the range 0-50 Brix with 1-decimal place accuracy making it ideal for use in factory or lab, particularly within food and beverage production as well as other indutrial sectors where temperature control is not required.
- Alpha-numeric keypad for easy data entry
- Flat sapphire prism surface for easy-cleaning
- Simple operation for factory environments
- Selectable read type: Continual, single, intelligent auto-sense
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 RFM700-M ideal for use in a harsh factory environment or busy 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.
