Atago PEN-Wrestling [3749] Digital Refractometer, 1 to 1.06 Urine Specific Gravity Range

The Atago 3741 PEN-Wrestling is a handheld, pen-shaped, digital refractometer that measures urine specific gravity (SG) in a 1.0000 to 1.0600 range, has external light interference (ELI) warning, automatic temperature compensation (ATC), and is commonly used by athletes. A refractometer measures the refractive index of a liquid or solid in a sample, converts it to concentration in units of percent by weight, and displays the results. Refractometers are commonly used in the optical, chemical, geological, ecological, culinary, food and beverage, pharmaceutical, and educational industries, and for water-testing applications.

This refractometer has a compact, ergonomic, pen-shaped body (16 x 3.8 x 1.8cm), with a thin prism head for one-handed operation, and two measurement process options. A sample is measured by dipping, touching, or stirring the tip into the sample. The unit has automatic temperature compensation (ATC) for immediate, accurate calibration readings, regardless of ambient temperature, and can be calibrated with water. An external light interference (ELI) feature displays a warning message when direct light is detected. A zero key provides easy reset capability. The body has Ingress Protection (IP)-65 rating for protection against dust and low pressure water, and the prism head has IP-67 rating for protection against dust and liquid immersion, and ease of cleaning. The 3741 PEN-Wrestling digital LCD displays measurement values in two seconds. This device comes with a strap holder, and plastic protective carrying case that snaps closed.
