The hopper scale on-site weightless calibration device consists of a pressure gauge, a screw jack and a special loading mechanism. According to the principle of superimposed force measuring machine, it is a set of devices (equipment) to determine whether the scale is in normal state by comparing the output data of the pressure meter and the load cell on the scale. It is suitable for calibration of weighing equipment made of application modules and for large tonnages where small table weights cannot be placed and for hopper scales.

Rapid Calibration for Reactor Weighing is an innovative calibration method for tanks, reactors, hoppers and silo scales. It ensures that accurate calibration results are achieved while at the same time meeting the traceability requirements of various quality control systems. Traditional calibration methods are time-consuming, expensive and often uncertain in terms of accuracy and traceability of calibration results. The innovative Weigh Tank Rapid Calibration is a traceable and economical method of calibrating tank scales without the use of test weights or purified water. It also eliminates the risk of contamination inside the tank by eliminating the costly and risky process of material substitution.
