 Our Product Strength

High Precesion Balances incorporate advanced Electro Magnetic Force Compensation technology for offering unmatched accuracy and reliability. coupled with unique ADC circuit with inbuilt temperature compensation on a specially developed ceramic substrate and using surface mounted devices coated with special durez compound offers a very high stability upto a resolution of 2 million counts in all weather conditions. All adjustments like Scale factor, linearity correction factor, temperature correction factor, response time, stability band width auto zero tracking and Display updation - all are programmable through the serial port to take care of any minor mismatch of different sub assemblies of balances

All Balances are tested for atleast 7 days and weight readings are taken at regular intervals, corrected for any deviation  by hardware and software adjustments so as to make the balance display readings within the permissible error limits depending on the accuracy class against standard weights throughout the duration of working within the specified limits of ambient temperature.
