The Digital Hand-Held Urine Specific Gravity Pen Refractometer utilises the refractive index method to measure the specific gravity of urine.
The "pen" type refractometer is extremely easy to use. Simply dip the tip into the sample and press the "START" key or press the "START" key and touch the tip into the sample and the result appears in 2 seconds.
The pen means less pipetting of the sample and therefore saving valuable time.
