Mettler JL802-G/A03 has been discontinued by Mettler and no longer in production. Mettler now only offers the JL602-G/L01 (610g x 0.01g) and JL6001-G/L01 (6100g x 0.1g) for portable jewelry scales.

The information below is for people researching and existing JL802-G/A03 for reference only since we are sold out and Mettler is not making this model anymore.

Mettler Toledo JL802-G/A03 gem balance is an affordable jewelry scale offering precise readabilities for legal for trade weighing applications.  This legal for trade Class II scale from Mettler also feature an RS232 interface as well as parts counting and percent weighing functions.  The RS232 interface allows you to connect the scale to Mettler's optional auxiliary display so the customer can see the weight while you are standing on the opposite side of the jewelry case.  You also can use the RS-232 interface to connect the scale to a Mettler printer or computer for data acquisition.

JL802-G/A gem balances weigh up to 810 grams in 0.01 gram increments when in Non-NTEP mode.  When in NTEP mode, the gem balance's readability decreases to 0.1 grams. 

Mettler Toledo is a world renowned manufacturer of scales and balances.  Mettler Toledo spends time and money on getting their products NTEP approved so jewelers can sell items by weight and not worry about having their balances confiscated. Anyone working with gold, platinum, silver or rhodium needs accurate weighing results and can't afford to give away anything.  You can have complete confidence and precision weighing results with METTLER TOLEDO BALANCES.

If you are look for our lowest cost legal for trade Class II digital scale be sure to see the A&D EK-1200i priced under $300.

Although the Mettler JL scale is legal for trade, if you plan on doing something like selling jewelry directly to customers in your store, then you are required by weights and measures to have a secondary display that the customer can see in real time. Another example might be if you've ever bought meat from a grocery store, you know that when the butcher weighs out the meat, you and the butcher both have separate displays as the meat is weighed. This scale is legal for trade, but it is NOT "legal for direct sales" unless you buy the Remote display with backlight.
