Sper 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 Sper Scientific refractometers come complete with:
- Rubber coated hand grip and construction which insulate the test solution from inaccuracies caused by the body heat of the user
- Covered eye piece and bright clearly defined scale, with large easy to read measurements
- All the accessories necessary for immediate use, including calibration tools and solutions, full instructions, transfer pipettes, protective cases, and a reference block for model 300004
SUGAR/BRIX REFRACTOMETER 0-32% 300001
The most popular refractometer range due to its usefulness in a wide variety of quality control applications for the sugar content of fruit, fruit juices, wine, milk, soft drinks and yeast cultures solutions. Also used for industrial cutting, lubricating, soluble tempering oils and emulsification solutions. Comes with a hard carrying case, calibration solution, and calibration tool. SUGAR/BRIX REFRACTOMETER W/ATC 0-32% 300010
This refractometer features Automatic Temperature Compensation (ATC), which makes manual temperature corrections unnecessary. The most popular refractometer range due to its usefulness in a wide variety of quality control applications for the sugar content of fruit, fruit juices, wine, milk, soft drinks and yeast cultures solutions. Also used for industrial cutting, lubricating, soluble tempering oils and emulsification solutions. Comes with a hard carrying case, calibration solution, and calibration tool.
SUGAR REFRACTOMETER 28-62% 300002
Use to test solutions with a higher sugar content, such as fruit juice concentrates, canned fruits containing added sugar, or ketchup as well as for egg yolk. Comes with a hard carrying case, calibration solution, and calibration tool.
CLINICAL REFRACTOMETER 300005
Measures protein concentration, urine specific gravity, or gives the refractive index in seconds using only a few drops of blood serum, plasma, urine or albumen. Comes with a hard carrying case, calibration solution, and calibration tool. SALT REFRACTOMETER 300006
Measures salt content in sea water, aquariums, breeding ponds, or pickling-brines. 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, and acetic acid (vinegar), when tested against a known standard. Comes with a hard carrying case, calibration solution, and calibration tool.
SALT REFRACTOMETER W/ATC 300011
This refractometer 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, aquariums, breeding ponds, or pickling-brines. 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, and acetic acid (vinegar), when tested against a known standard. Comes with a hard carrying case, calibration solution, and calibration tool.
BATTERY COOLANT REFRACTOMETER 300014
Measures the freezing point of automotive coolants in their current concentration as well as battery charge. Both ethylene glycol and propylene glycol antifreezes can be measured, on separate scales. Battery charge is measured on a third scale using just a few drops of battery electrolyte solution (battery acid). The specific gravity of the battery acid is displayed together with a reading of RECHARGE, FAIR, or GOOD. Comes with a hard carrying case, calibration solution, and calibration tool.
