Discontinued: A&D has discontinued the GP-30KN. The closest current model is the A&D GX-32001LN. The GX-32001LN has NTEP Class II approval (legal for trade in 1 g steps, e = 1 g; the GP-30KN read to 0.1 g), internal calibration, and more capacity (32 kg vs. 31 kg). It ships free in the continental U.S.

Description
A&D GP-30KN NTEP High-Capacity Balance: 31 kg × 0.1 g (Discontinued, Replaced by the GX-32001LN)
The A&D GP-30KN is discontinued. The closest current model is the A&D GX-32001LN, which has NTEP Class II approval (legal for trade in 1 g steps, e = 1 g; the GP-30KN read to 0.1 g), internal calibration, and more capacity (32 kg vs. 31 kg). The specs below are kept for reference and for owners of the GP-30KN.
The A&D Weighing GP-30KN was the NTEP Class II legal-for-trade version of A&D’s GP-30K high-capacity balance. It weighs up to 31 kg in 0.1 g steps on a 384 × 344 mm pan, with internal calibration and IP65 dust and water protection. A&D has discontinued it; the NTEP Apollo GX-32001LN is the closest current model.

Calibration for the GP-30KN and GX-32001LN
Already own an A&D GP-30KN? Our TDA-registered technicians calibrate it in-house, by mail-in or in our Houston-area shop, and include a certificate. Buying the replacement GX-32001LN? Add calibration to that order and it ships calibrated:
- In-house calibration with certificate, using NIST-tested weights: $250. We calibrate and verify your GP-30KN with NIST-tested weights and include a calibration certificate, so it arrives set up and accurate. Add $250 calibration to cart
- NIST calibration with a NIST-traceable certificate: $595. Full calibration documented on a NIST-traceable certificate, for labs, QC programs, and audits that need a paper trail. Add $595 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
Is the A&D GP-30KN discontinued?
Yes. A&D has discontinued it; the GX-32001LN is the closest current model.
What should I buy instead of the A&D GP-30KN?
The A&D GX-32001LN, with NTEP Class II approval (legal for trade in 1 g steps, e = 1 g; the GP-30KN read to 0.1 g), internal calibration, and more capacity (32 kg vs. 31 kg). Call us at (832) 290-3120 and we’ll help you move to the new model.
Can MNM Scales calibrate my GP-30KN?
Yes. Choose in-house calibration with a certificate, using NIST-tested weights, for $250, or NIST calibration with a NIST-traceable certificate for $595.
