Ultra Class

For laboratory balances and applications that demand superior accuracy, Ultra Class weights feature weight tolerances that are 40 to 50% tighter than ASTM Class 1 and equal to, or exceeding OIML Class E2. Masses are polished stainless steel and supplied in a protective case. A handling glove is included. Models are available with NIST Traceable or NVLAP Certifications.
