Description
A&D GX-1603A Apollo Precision Balance: 1620 g × 0.001 g
The A&D Weighing GX-1603A is the 1620 g milligram model in A&D’s Apollo GX-A series. It weighs up to 1620 g in 0.001 g steps, settles in about one second with Smart-SHS technology, and calibrates itself automatically based on time and temperature.
Impact shock detection warns you, visually and audibly, when the balance takes a hit and logs the event. Data stays protected with passwords for up to 11 users and an administrator, and RS-232C and USB are built in.
Key Features
- 1620 g × 0.001 g; repeatability 0.001 g; linearity ±0.003 g
- Automatic internal calibration triggered by temperature and time
- Smart-SHS for about 1-second stabilization
- Impact shock detection with alerts and logging
- Passwords for 11 users and 1 administrator; GLP/GMP/GCP compliant output
- RS-232C and USB
- 128 × 128 mm stainless pan and removable dust plate
- IP54, die-cast aluminum housing, backlit LCD with 6 keys
- Flow rate display, underhook weighing, density determination
- 5-year A&D limited warranty
Applications
Laboratories and Formulation
Weigh larger containers, up to 1620 g, to 1 mg with automatic calibration that keeps results accurate through the day.
Pharmacy Compounding and QC
Document results with GLP output and password-protected settings.
Jewelry and Gems
Weigh gemstones, findings, and jewelry in carats, pennyweight, and troy ounces. The balance is not NTEP approved; for buying or selling precious metals by weight, choose an NTEP Class II balance such as the A&D GX-403AN.

Calibration Options from MNM Scales
Get your GX-1603A 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-1603A 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.
