Item 0663C BALANCE - Mettler AT 20 balance

Mettler Toledo AT20 analytical balance

  • Readability to 2ug,22g capacity
  • Fully automated self-adjustment
  • Includes LC-P45 printer
  • 90 day warranty

Mettler AT series analytical balances have been a consistent seller for many years, and with good reason. These balances are easy to use and feature quick warm up time, auto and manual draft shield options, and up to ten selectable weighing units. The Mettler AT20 also included Mettler’s proFACT three-point self-calibration program. Any time the balance senses a change in ambient temperature, two motor-driven internal calibration weights automatically adjust the linearity of the balance with reference to three fixed points across the weighing range. In other words, the balance automatically self-calibrates as needed in order to provide accurate weighing despite temperature fluctuation.

In addition to the proFACT, the balance has easy to use menu operated calibrations: motorized internal calibration, including linearity calibration, by built in 2 standard weights and external calibration by 20g weight. Balance operating menu allows to adapt the balance to weighing conditions, select calibration function, weighing process adapter, repeatability, auto zero correction, primary and alternative weighing units and interface output parameters.

This balance also comes with an LC-P45 dot matrix printer. It can supplement the weight value with date, time and other data. It has two LocalCAN interfaces and one RS-232-C interface.

Our technicians test balances to insure repeatability, correct cornerload tolerances, linearity, and reduced span at or near full capacity. We also test all displays and controls as well as any other features that are included, such as auto-calibration and draft shield auto-retraction, to make sure the balances are fully operational.
