The Clinic-Chek is a multi-scale clinical refractometer ideally suited for the medical clinic, laboratory, and for athletic/wrestling hydration measurement.  Three measurements scales in one model allows more flexibility and cost savings to you.  The Clinic-Chek is more accurate than hydrometers and test strips.

The Clinic-Chek is easy to operate and provides quick results. Its LCD digital display is easy to read and removes the subjectivity of shadow line interpretation across a small scale used in conventional handheld refractometers.  Reading errors are eliminated with this easy-to-use clinical refractometer.

Measure body fluids (Urine and Blood Serum) without placing the sample near your face as required with other optical manual models.  This measurement is safer and more convenient.

Durable storage case included - Optional holster available.
