SINGLE PAN ANALYTICAL BALANCES

It is an old-established fact that true single-pan design eliminates the causes of certain weighing errors inherent in the design of the conventional, equal arm, two-pan balance. METTLER has pioneered in this field and today maintains its leadership through intensive research and development work. From an analytical model with 1 0 0 0 grams capacity to the excellent micro balance with 20 grams capacity, there are a number of different models, a d a p t e d for various operating conditions. W r i t e us and let us show you how a METTLER balance can meet your specific requirements. # Our plant in Hightstown, N. J. is equipped to deal with any maintenance or repair problems on METTLER instruments.
