MASTER-50H is heat resistant model of the MASTER-Series. The MASTER-50H is the successor model of the conventional model, H-50. The MASTER-50H is developed for measuring high-temperature samples at their respective production sites. Moreover, the MASTER-50H has a longer service life as compared with conventional types because its prism is made of corrosion resisting tempered glass. * 以 10% 蔗糖溶液 ( RE-110010 ), 30% 蔗糖溶液 ( RE-110030 ) 或 50% 蔗糖溶液 ( RE-110050 ) 作為刻度設(shè)定
