Precise Measurements, Advanced Features and Readings in Multiple Scales

Laboratory Digital Refractometers are easy to use and calibrate using distilled water. You can measure brix, salinity, refractive index and clinical parameters with full-scale accuracy of 0.1%. Each requires just a 0.4mL sample to instantly display temperature along with multiple scales.
Specifications: Each features automatic calibration, automatic temperature compensation, automatic shut-off after three minutes and visual high/low alarms. Water-resistant design allows easy cleanup. Low power consumption means you get up to 5000 readings before the LCD indicates battery replacement. Includes a 9V battery, distilled water, a transfer pipet, instructions and a protective case.
