    Doublechecking Digital Refractometer

    I already own a delicate, glass hydrometer from Dupla. Plan on buying a digital refractometer, the Hanna one specifically. Should I own a handheld refractometer to double check the digital refractometer? The Vee Gee STX-3 is a bit of an investment, but I can't doublecheck with the hydrometer...
