• Features Automatic Temperature Compensation (ATC), which makes manual temperature corrections unnecessary
• Double scale in parts per thousand and specific gravity
• Measures salt content
• 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
• Portable refractometers work in ambient light with no battery or other power source necessary
• Commonly used to help identify or confirm the identity of a sample, assess the purity of a sample, or determine the concentration of a solute in a solution
• Simply place a drop or two of a sample on the prism and read the results immediately

Comes complete with:
• Rubber coated hand grip and construction, which insulate the test solution from inaccuracies caused by the user's body heat
• Covered eye piece and bright, clearly defined scale, with large easy-to-read measurements
• All the accessories for immediate use, including calibration tools and solutions, full instructions, transfer pipettes, and protective cases

Cat. No. 330-33106 includes a Certificate of Calibration specifies that the product has been tested and found to be within its stated tolerance for accuracy. These products can be adjusted to the standard they are tested against.
