Digital Refractometer for Seawater Analysis

• Designed for seawater salinity analysis
• High accuracy measurements displayed as PSU, ppt and specific gravity
• 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 adversely affect readings
• IP65 Water Protection: built to perform under the harsh field conditions associated with environments containing seawater
• Readings are displayed in approximately 1.5 seconds
• Calibrate with distilled or deionized water
• Sample can be as small as 2 metric drops
• Automatic shut-off after three minutes of non-use
• Stainless Steel Sample Well: easy to clean and corrosion-resistant
