They also deliver all the statistics needed for Good Laboratory Practice.Fully automatic internal calibration （proFACT®） comes with history function, initiated by time and/or when the ambient temperature changes by either 1, 2, or 3°C. Models 11278-320, 11278-324, ａnd 11278-330 feature DeltaRange® capabilities, which deliver ten times the readability anywhere within the balance range just by taring. Operating menu can be viewed in English, German, French, Spanish, Italian, Russian, ａnd Japanese. The operating software can be upgraded via the Internet. All models will display 12 different weighing units ａnd available applications include statistics, formulation, piece counting, percent weighing, ａnd density. Settings can be password protected. The level ａnd the minimum weight per USP can be monitored by user.All models feature the unique SmartGrid™ weighing pan, which is supported at the rear of the weighing chamber, for more efficient weighing. The SmartGrid™ weighing pan has only minimal solid area to minimize buoyancy caused by turbulance, shortening stabilization time for faster results. In combination with the optional weighing kit （11276-932）, which includes ErgoClips®, the SmartGrid™ weighing pan becomes an ergonomic weighing system that can be precisely adapted to specific tasks ａnd can help to increase productivity. ErgoClips® click securely onto the grid weighing pan ａnd can hold round-bottom flasks, test tubes, plastic tubes, ａnd more.Each model features stainless steel pan, color display with touch screen operation, sensors for hands-free operation, protective cover for terminal ａnd weighing platform, ａnd feedthrough for below-the-balance weighing.
