Mettler's JB1203-L-C/A has a weighing capacity of 240 grams and increments in 0.001 gram divisions.  This is an extremely affordable milligram balance that comes with the external 200 gram calibration mass, RS-232 interface, and 3 door glass draftshield for stable and accurate weighing results.

Mettler Toledo's JB1203 carat balance offers milligram precision in standard mode or 0.01 ct/g readabilities in NTEP mode.  Jewelers looking for a legal for trade gem balance can trust Mettler Toledo to deliver precision weighing results every time.

We don't sell many of the Mettler-Toledo JB1203-L-C/A since this digital balance offers external calibration only and for a little more money you can buy JB1203-C/A-F which offers automatic internal calibration with the same weighing specification.

As the price of precious metals like gold, platinum, silver and rhodium keep raising customer complaints to weights and measures officials are on the increase.  The general public is calling complaining they are being short changed buying and selling by weight.  These complaints typically result in a Weights & Measures officials doing an inspection to verify the scale in use is Legal for Trade. Most pawnshops, jewelers and metals buyers know they need a Legal for Trade Type Approved Scale, but these inspectors are now requiring the weighing scale to have two displays to meet the requirements of "direct sales". In weights and measures terminology a direct sale is one where both the buyer and seller are present.  NIST Handbook 44 requires the customer to be able to witness the transaction and transaction information from a reasonable position in a direct sale application. Weight indications shall be shown on the customer’s side of the scale when used for direct sales to retail customers.  The way to achieve these requirements is to purchase the optional display shown above (purchase here).  The Mettler Toledo 72213564 remote display features a backlight.  The display plugs into the RS-232 port on the back of the balance and the cable length is 6 feet.  All Mettler JB and JL balances are equipped with RS-232 interface with the exception of the JL602-G/LA00 and JL6001-G/LA00. The Mettler Toledo JB and JL Scales we offer meet or exceed the Class II or III accuracy requirements in accordance with the National Institute of Standards and Technology (NIST) Handbook 44.  Certificate of Conformance Numbers are issued under the National Type Evaluation Program (NTEP) of the National Conference on Weights and Measures.  NTEP approved Mettler Balances make it easy to comply with current regulations for the direct sales to the public of precious metals and semi-precious gems.
