Description
Salt Refractometer w/ATC, 0 to 100 ppt 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 chloride, barium cobalt, magnesium, cesium, potassium, sodium chloride, cupric sulfate, potassium iodide, citric acid, acetic acid and (vinegar), when tested against a known standard.
Sper Scientific portable refractometers work in ambient light with no battery or other power source necessary. Simply place a drop or two of a sample on the prism and read the results immediately. Cat. No. 330-33106 includes a NIST Traceable Certificate of Calibration .
