Features

Mass comparators of UMA 5 series stand for the highest standard of professional automatic mass comparators. They provide comparison of 1 mg – 5 g weights of E1 and lower classes. The device is equipped with 36 magazine positions allowing to deposit up to 36 weights. This solution allows to perform either comparison for complete set of weights carried out within one process or comparison for just a few weights of the same mass. Owing to elimination of human factor and with temperature changes and air drafts reduced to zero, UMA automatic mass comparators provide the highest possible measurement repeatability.

• Effective and Excellent Measurement The UMA series stands for a class-leading automatic mass comparator. These comparators enable comparison of 1 mg - 1000 g weights of class E1 and lower.
• Comparison of Mass Standard Sets The UMA mass comparator is equipped with either 18-position or 36-position magazine. This universal solution enables comparison of whole weight sets during one process, however using it you can also compare weights of the same mass.
• Excellent Measurement Repeatability UMA automatic mass comparator, due to the elimination of the human factor, temperature changes and air drafts, guarantees excellent measurement repeatability.
• Vibration Sensor With vibration sensor placed inside the electronics, the UMA mass comparators analyse and identify vibration sources. The sensor helps to determine whether the recorded vibrations influence the measurement result or not.
• Dedicated Software Thanks to a user-friendly and functional software the user can prepare complete calibration schedule within just a few minutes.
• Universal Insert Shape Insert design allows measurement of weight of very small mass with high accuracy and prevents weight jamming. The device enables comparison of weight of various shapes using just one universal insert.
