Digital Refractometer for Measuring Sodium in Food

The sodium chloride refractometer meets the requirements of the food industry. This optical instrument employs the measurement of the refractive index to determine sodium chloride concentration in aqueous solutions used in food preparation. It is not intended for seawater salinity measurements.

Features

• High accuracy measurements in g/100 g, g/100mL, specific gravity and °Baume
• Dual-level LCD displays measurement and temperature readings simultaneously
• Automatic temperature compensation
• Easy Measurement: place a few drops of the sample in the well and press the READ key
• Alerts the user of low battery power that could adversley affect readings
• IP65 Water Protection: built to perform under harsh laboratory and field conditions
• Readings are displayed in approximately 1.5 seconds
• Calibrate with distilled or deionized water
