Medical professionals and lab technicians, this Atago 3741 digital refractometer makes measuring urine specific gravity quick and accurate! The pen-shaped design is super convenient for one-handed operation, measuring in just 2 seconds with ±0.0010 accuracy across a 1.0000 to 1.0600 SG range. It uses the refractive index method - just dip, touch, or stir the tip in your sample and get an instant digital reading on the LCD display. The automatic temperature compensation means you get accurate results regardless of ambient temperature between 10-40°C. The IP-65 rated body protects against dust and water, while the prism head has IP-67 rating and can even be immersed for easy cleaning. It's powered by a single AAA battery (included) and weighs only 70g, making it portable enough for clinic use or field work. The external light interference warning alerts you if direct light is affecting your measurement, and the zero key makes calibration with water simple. It comes with a protective carrying case and strap holder for convenience. Whether you're in veterinary medicine, clinical labs, or research, this handheld refractometer delivers laboratory-grade accuracy in a compact, easy-to-use package. If you're tired of traditional urinometers or want faster, more reliable SG measurements without the mess and reading errors of float methods, this digital pen refractometer provides that professional precision with the convenience of modern technology.
