Vendor may be running site-wide discounts, but still inquire with MSE for the best price. Measure concentrations in brix, salinity, refractive index and clinical parameters with full-scale accuracy of 0.1% using CCD scanner (linear scanned array imaging) technology. Simple to use. All models calibrate to distilled water and require a sample of only 0.4 ml. Instantly displays temperature in addition to multiple scales with the unit of measure indicated on the large LCD. The sophisticated microprocessor provides automatic calibration, automatic temperature compensation, automatic shutoff (after 3 minutes), and visual min/max alarms. Low power consumption enables 5000 readings, before the LCD indicates that the battery should be replaced. The water-resistant design protects the electronics from wet environments and makes for easy cleanups. Comes ready to use with a 9V battery, distilled water, a transfer-pipet, instructions and a protective case.
