High Precision Balances (without motorized internal calibration) ( 0.001g to 1000g )
Manufacturers, Suppliers and Exporters


Contech High Precision Balances incorporate advanced Electro Magnetic Force Compensation (EMFC) technology for offering unmatched accuracy and reliability, coupled with unique ADC circuit with inbuilt temperature compensation to offer a very high stability upto a resolution of 6 million counts. All adjustment parameters are programmable to take care of any minor mismatch of different sub assemblies & Balances are configured with these parameters.

ANALYTICAL (Direct Loading) BALANCES 0.0001g to 220g

  • Backlite LCD Display : Customized, large, attractive LCD with multiparameter display illuminated by white backlite.
