MA872 Digital Refractometer for Fructose Measurements
The MA872 is an optical instrument that employs the measurement of refractive index to determine the % Fructose in aqueous solutions. The method is both simple and quick.
Samples from expressed, reconstituted or concentrated juice are measured after a simple user calibration with steam distilled water (starter bottle provided with your unit). Within seconds the instrument measures the refractive index of the sample and converts it to % by weight concentration units.
The MA872 digital refractometer eliminates the uncertainity associated with mechanical refractometers and is easily portable for measurements in the plant.
The measurement technique and temperature compensation employ methodology recommended in the ICUMSA Methods Book (Internationally recognized body for Sugar Analysis).
Temperature (in °C or °F) is displayed simultaneously with the measurement on the large dual level display along with icons for Low Power and other helpful message codes.
Key features include:
• Dual-level LCD
• Automatic Temperature Compensation (ATC)
• Easy setup and storage
• Battery operation with Low Power indicator (BEPS)
• Automatically turns off after 3 minutes of non-use.
Conductivity readings are performed by applying an alternate current to the 4-ring probe which creates a variable voltage depending on the conductivity.
