These scientific portable refractometers work in ambient light with no battery or other power source necessary. They can be used in labs, on production lines, in the field, or anywhere. Simply place a drop or two of sample on the prism and read the results immediately. With reasonable care their reliability, precision, and optical performance will last forever. All North Coast refractometers come complete with:

  • Rubber coated hand grip and construction which insulates the test solution from inaccuracies caused by the body heat of the user.

  • Covered eye piece and bright, clearly defined scale for easy-to-read measurements.

  • All the accessories necessary for immediate use, including calibration tools (if necessary), full instructions, transfer pipette and a protective case
