Digital Refractometer, 1.3330 to 1.3900 RI , 0 - 14 g/dl Serum Protein, Urine Specific Gravity (animal), 1.000 - 1.060 g/dl

Never wait for readings again|Rugged design is IP65 rated Easy calibration for precise results at all times No more worrying about temperature fluctuations with built-in ATC|These digital refractometers feature an LCD, eliminating reading errors with common handheld refractometers. All models feature built-in automatic temperature compensation (ATC) which removes temperature fluctuations allowing the user to concentrate on the measurements. The compensation range is 41 to 104?F (5 to 40?C). Many range options are available for measurements within any application. All models also feature a zero% adjust with distilled water, allowing for immediate and easy calibration for precise measurements at all times. The battery life for these units is ?5000 readings.
