Product Information
Gold doesn’t forgive a bad scale. A few milligrams of drift on a busy counter adds up fast, whether it’s coming out of your margin or a customer’s trust. That’s why precious metals dealers, jewelers, refineries, and assay offices across the region standardize on Mettler Toledo. These four instruments cover the full weighing chain, from retail counter to laboratory bench, each one built to a level of accuracy that holds up to scrutiny and pays for itself in disputes you never have.

FAQ
What’s the difference between the JET303G/00 and JET4002G/00?
Capacity and readability. The JET303G/00 reads to 1 mg on pieces up to 320 g, built for fine jewelry at the retail counter. The JET4002G/00 reads to 10 mg on loads up to 4,200 g, built for bars, scrap, and bulk trading where volume matters more than sub-milligram detail.
Are these balances legal for trade in Saudi Arabia and the GCC?
The standard units listed here aren’t certified out of the box, but OIML legal-for-trade versions are available on request for all four models. GSS handles the SASO-aligned certification and paperwork as part of the sale.
Can the JL1502GE run without mains power?
Yes. It runs on 4 AA batteries for 8 to 15 hours, or on the included AC/DC adapter. That makes it the right choice for site valuations, buy-back events, or any location without reliable power.
What is the WXTJ3DU actually used for?
It’s an OEM-grade weigh module built into laboratory balances and integrated systems, used for diamonds, gemstones, and micro gold samples where standard milligram readability isn’t precise enough. Refineries and assay or hallmarking labs use it to certify purity and stone weight to a microgram.
Do these balances display gold trade units like tola, baht, and mesghal?
Yes. The JET303G/00, JET4002G/00, and JL1502GE all support 16 switchable weighing units, including tola, baht, mesghal, and troy ounce, with two units shown simultaneously on screen.
Does GSS handle calibration and servicing after purchase?
Yes. As Mettler Toledo‘s official partner for Saudi Arabia and the GCC, GSS provides calibration certificates, servicing, and compliance support from offices in Riyadh, Jeddah, Dammam, and Dubai.
Can I add gold purity verification to a JET balance I already own?
On the JET303G/00 and JET4002G/00, yes. Both are compatible with an optional density determination kit, letting you offer purity verification as a service without replacing your equipment.
