Atago have released a new pen sized refractometer for measuring urine specific gravity. The PEN-URINE S.G. is ideal for sports coaches, hospitals and OH&S administrators as it is quick and easy to use. Simply press the start button then dip the end of the refractometer in the sample and stir - it will continue to create measurements until the readings become stable.

Urine specific gravity (USG) is a laboratory test that measures the concentration of particles in the urine. In clinical pathology USG is commonly used to evaluate kidney function.  While athletes and OH&S administrators use USG to make sure individuals consume enough water during strenuous activity.

Urine specific gravity (the concentration of these excreted particles in urine) is generally expressed in grams/millilitre (g/mL). The PEN-URINE S.G, which features automatic temperature compensation (10 - 40°C), has a measurement range of 1.0000 – 1.0600 Urine S.G (accuracy ±0.0010). A normal specific gravity value ranges from 1.002 to 1.028 g/mL.

The PEN-URINE S.G is water resistant, making it quick and easy to clean – just rinse with water and it is ready to be used again.
