There's nothing like this available anywhere! This is THE unit to test athletic HYDRATION! This is THE unit for Veterinarians! One NEW ZGRC-200ATC tri-scale portable Clinical Refractometer in a blue, foam-lined hard case. The ZGRC series of portable refractometers is designed to measure Urine Specific Gravity, Blood Plasma Serum Protein and Refractive Index, but includes the benefit of an internal light. The extra light can be turned on when the ambient light is so-so, and when light is good, you can turn off the light and use the unit! You can use the unit without batteries (3, 1.5 volt button batteries) to conserve power! One scale checks Blood Plasma Serum Protein with the range of 0-12 g/dl, another checks for Urine Specific Gravity with a range of 1.000 to 1.050 and the last scale gauges Refractive Index with a range of 1.330 to 1.360 (divisions of 0.2 ppt or 0.005 Specific Gravity) . Models with the “ATC” suffix are equipped with “Automatic Temperature Compensation” for accurate measurements without re-calibration after shifts in ambient working temperature (field use). Included are: a pipette for dropping test fluids onto the prism (never dip the refractometer into the test fluid!), a mini screwdriver for scale calibration, (3) 1.5 volt button batteries, and a Users Guide.
