True saltwater salinity refractometer boasts quick and accurate measurement. Features the largest, sharpest scale display for the most accurate salinity and specific gravity readings available (±1.0% salinity and ±0.001 specific gravity). Unlike some models, the Vital Sine Refractometer is a true seawater salinity unit designed specifically for use with seawater and not just brine solutions.
Easy, no-tool calibration with automatic compensation for shifts in ambient temperature (from 10°- 30°C). Compact and portable for use anywhere. Metal housing and rubber hood protect unit and prevent light from entering eyepiece. Features built-in calibration ring, no-roll stand, rubber grip to insulate against hand heat, storage case, instructions, and more. Range: 0 - 100 parts per thousand salinity, 1.000-1.070 specific gravity.
Pinpoint 53.0 µS Calibration/Reference Fluid sold separately.
