This balance comes with a 100 gram ASTM class 1 calibration weight, dust cover and RS-232 interface for connection to a computer or optional Sartorius printer.  Only the Sartorius GD-503 comes standard with these items while competitive models typical charge $70 to $100 for the calibration weight and $40 for a dust cover.  Plus the GD503 has a 3 year manufacturer warranty.

Sartorius is a German company and maker of some of the world's finest balances since 1871 when they introduced the world's first pharmaceutical balance.  Only Sartorius shatters the limits when "the Guinness Book of World Records" listed the Sartorius Model 4108 as the most accurate balance in the world.

A big selling point on the GD-503 in the low profile 5.23 inch high Draft Shield Chamber (height from pan to top of glass door).  The two side doors and top door slide open for fast & easy access to the weighing chamber.  Jeweler's have limited space in their stores and the small footprint makes the Sartorius GD503 a big selling point.

We believe the GD503 is the best 3 decimal place carat scale on the market for price, performance, features and quality.  Made in the USA and engineered & designed by the best metrology engineers that Göttingen Germany has at Sartorius' advance weighing technology research lab.

All used balances are pending availability.

Innovative high-grade draft shield with low profile design resulting in less bench space compared to conventional analytical balances (height from pan to top of glass door is only 5.23 inch).  Draft shield offers 3 sliding doors that slide open quietly and effortlessly.		Leveling the balance with the 2 front adjustable feet is a breeze.  The identification badge is located on the left side of the GD503 Class II NTEP Approved Balance in accordance to National Conference on Weights and Measures.

Bottom side of GD503 balance shows the two front adjustable feet and tamper evident sticker across access plate and the balance housing.		When the balance is used in legal metrology (a.k.a NTEP mode) external calibration is blocked by a seal over the access plate.
In accordance with weights and measures regulation the balance must be sealed to prevent tampering and re-calibration once the balance is placed in service.  To prevent access to the calibration switch a tamper evident seal is placed across the access plate and bottom housing. The Weights and Measures Inspector will place this seal on the balance once the inspector has tested the balance and places the balance in service as a legal for trade device.
Handbook 44 requires the identification badge specify the model number, serial number, "d" - display division, "e" - verification scale interval and the National Type Evaluation Program Certificate of Conformance (NTEP CC)
Balance is set to non-NTEP mode since the least significant digit is not "boxed"
