A mass comparator and a regular balance are built on the same principles. However, the weighing cell used in a mass comparator is carefully selected for its exceptional performance, particularly in terms of its repeatability specifications. In general, the repeatability of a mass comparator is better than that of a regular balance. Comparator balances are often equipped with self-centering weighing pans, called LevelMatic. These special weighing pans automatically adjust to the center of gravity of the weight, eliminating eccentricity errors. These features, coupled with the high repeatability, make comparator balances particularly suited to mass calibration and mass verification applications. However, an increasing number of customers are choosing a manual mass comparator when they require a high level of weighing accuracy.
While a full range comparator can determine any weight up to its maximum capacity, the window-range comparator can weigh only in a window around its target range. However, due to the smaller weight range, window-range comparators have the better repeatability and readability.
Mass comparators as the name implies, are made to compare masses. Namely, a test weight with an unknown weight is compared with a reference weight with a well-known weight. Some comparators are specifically made to compare weights, the so-called window-range comparators, others are simply balances with exceptional weighing performance.
The METTLER TOLEDO Susceptometer is compatible with several instruments, including the XPR6UD5, XPR6U, XPR10, and XPR10U. These balances allow for seamless integration and precise measurements when assessing the magnetic susceptibility of weights.
