E1 Mass Comparator

A mass comparator is a special type of electronic balance mainly used for comparing the mass of weights or objects with high precision requirements. Generally speaking, a mass comparator cannot directly read the mass of a weight, but instead displays the numerical value obtained by comparing the measured weight or object with a standard weight or object. If we know the mass of the standard weight, we can compare the measured weight with the standard weight multiple times using a mass comparator to obtain the difference between the measured weight and the standard weight, thereby obtaining the value of the measured weight. Due to the extremely high resolution and good repeatability of the mass comparator, accurate values can be obtained even if the difference between the measured weight and the standard weight is small. The D&T full range mass comparators have various functions, which can be used not only for measuring weights, but also for general weighing applications.
   The mass comparator is mainly used for weights verification, national standard mass laboratories, statutory metrological verification institutions, calibration laboratories, etc. At present, in the field of industrial mass control, mass comparators are increasingly showing their importance. For example, the determination of standard density and volume, coating wear caused by mechanical effects, membrane and coating weighing in the chemical industry, filling weighing of precious gases, and weighing of turbine blades.

Main feature

· Accurate weight measurement

The whole machine has super high resolution and very good repeatability, through the auto-centering pan to eliminate partial load , to ensure that you get the best measurement performance and traceability of weighing results.

· Measurement comparison of full range mg to ton weights

· Cover the full range measurement and mass calibration of class M to class E1 weights

· Auto-centering device (some models)

· Improve the accuracy of the weighing results, eliminate the partial load error, and accurately locate all types of items to the center of gravity, without manually adjusting the position of the weight on the scale plate.Electromechanical separation design (some models)

Mobile and separable display operation terminal, isolate the interference of electrical noise to the sensitive analog circuit; shorten stability time, improve the repeatability, and ensure the accuracy of measurement.
