More About this Item

These compact benchtop refractometers are ideal for measuring Brix, salinity, and refractive index with the full scale accuracy of 0.1%. The internal CCD scanner (linear scanned array imaging) provides accurate, reliable measurements. Units are simple to use – place at least 0.4 mL of sample on the surface of the prism, press READ, and the sample results are displayed in seconds. The meter instantly displays the measurement and temperature on the large, easy-to-read LCD.
The sophisticated microprocessor provides automatic calibration, automatic temperature compensation, low-battery indicator, automatic shutoff (after three minutes) and visual hi/low alarms. The durable, water-resistant design protects the electronics in wet environments and makes cleanup easy. All models calibrate to distilled water and feature a simple push-button interface and 5000 reading battery life.
