Hi...I'm not familiar with that particular brand, but, floating hydrometers generally are more accurate than plastic ones. However, the readings must be adjusted for temperature and I'm sure I don't have to tell you about the bobbing/floating away/back of the tank thing. I highly recommend that you invest in a refractometer. They run about $40 on Drs. Foster and Smith. SH
