Salt Refractometer with ATC - 0 to 100 PPT Nebo 0°C~500°C: ±2Sper Scientific portable refractometers work in ambient light with no battery or other power source necessary. Features Automatic Temperature Compensation (ATC), which makes manual temperature corrections unnecessary. Double scale in parts per thousand and specific gravity. Measures salt content in sea water, breeding ponds, or pickling brines and other applications. While the scale is calibrated for sodium chloride, it can also be used for calcium
