The VRFM732M Refractometer is a cost-effective and user-friendly solution with a 4" full-color display and robust switch membrane. It covers the full Brix range (0-100) with one-decimal-place accuracy, making it suitable for measuring sugar concentrations in various applications, particularly in the food and beverage manufacturing sector.

Designed for simplicity, the VRFM732M offers digital automatic technology without the need for complex temperature control. Its robust construction, including a sapphire prism in a stainless steel dish, ensures durability in harsh environments. It can operate in the °Brix scale, with results temperature-compensated to 20°C, and supports additional user scales for different measurements, such as wine, Refractive Index (RI), and FSII.

The RFM732M Series refractometers feature Span calibration for precise adjustments and AG temperature compensation for use with AG Fluids without conversion tables. This instrument is versatile, finding applications not only in the food and beverage industry but also in other non-food sectors requiring refractometric measurements. It comes with a certificate of conformity and is a reliable choice for quality control and measurement needs.
