A&D GX-403AN Apollo Precision Balance, 420 g x 0.001 g, Internal Calibration, NTEP Class II

Description

A&D GX-403AN Apollo Precision Balance: 420 g × 0.001 g

The A&D Weighing GX-403AN is the NTEP Class II, legal-for-trade version of the GX-403A milligram balance in A&D’s Apollo GX-A series. It weighs up to 420 g in 0.001 g steps on a 128 × 128 mm pan, and calibrates itself with a built-in weight.

A&D’s Smart-SHS sensor gives readings in about 1 second, and built-in self-checks help you keep records for SOPs and audits.

Key Features

• 420 g × 0.001 g; repeatability 0.001 g, linearity ±0.002 g
• NTEP Class II legal for trade (0.01 g in legal-for-trade mode)
• Internal calibration with one-touch CAL and Automatic Self-Calibration (time and temperature)
• Smart-SHS sensor, about 1-second stabilization
• ECL self-check runs a repeatability test without an external weight in about 90 seconds
• QuickMin-S and Min-S Alert for minimum sample weight
• Impact Shock Detection with shock log
• Flow Rate Display for filling and dosing
• Password protection for up to 11 users and 1 administrator
• RS-232C and USB standard; GLP/GMP/GCP output
• Front bubble level with LED and thumbwheel leveling feet

Applications

Laboratory and QC

Weigh samples, reagents, and standards to the milligram, with calibration reports for your records.

Formulation and Sample Prep

Use flow rate display and comparator modes for filling and dosing.

Jewelry and Gems

Weigh gemstones and findings in carats, pennyweight, and troy ounces. Because it is NTEP Class II approved, you can also buy and sell precious metals and gems by weight.

Legal-for-Trade Sales

Sell high-value goods by weight, with 0.01 g legal-for-trade resolution.

Calibration Options from MNM Scales

Get your GX-403AN calibrated and ready to use on day one. Add either option to your order, and our TDA-licensed technicians calibrate it in-house before it ships:

• In-house calibration with certificate, using NIST-tested weights: $95. We calibrate and verify your GX-403AN with NIST-tested weights and include a calibration certificate, so it arrives set up and accurate. Add $95 calibration to cart
• NIST calibration with a NIST-traceable certificate: $395. Full calibration documented on a NIST-traceable certificate, for labs, QC programs, and audits that need a paper trail. Add $395 NIST calibration to cart

We also recalibrate scales and balances you already own, by mail-in or in our shop, with on-site service across Houston and the surrounding area. Request calibration or call (832) 290-3120.

Frequently Asked Questions

Does the GX-403AN calibrate itself?

Yes. It has a built-in calibration weight, one-touch CAL, and Automatic Self-Calibration triggered by time or temperature change.

Is the GX-403AN legal for trade?

Yes. It is NTEP Class II approved and reads 0.01 g in legal-for-trade mode.

GX-403AN vs. GX-403A?

Same 420 g × 0.001 g balance with internal calibration. The GX-403A is not approved for legal-for-trade use.

Can MNM Scales calibrate the GX-403AN before it ships?

Yes. Choose in-house calibration with a certificate, using NIST-tested weights, for $95, or NIST calibration with a NIST-traceable certificate for $395.
