Description
A&D GP-20K High-Capacity Balance: 21 kg × 0.1 g with Internal Calibration (Discontinued, Replaced by the GX-22001L)
The A&D GP-20K is discontinued. A&D replaced it with the A&D GX-22001L, which has 0.1 g readability and internal calibration in a 22 kg capacity. The specs below are kept for reference and for owners of the GP-20K.
The A&D Weighing GP-20K is a high-capacity industrial balance from A&D’s GP series. It weighs up to 21 kg with 0.1 g readability using A&D’s double-leveraged Super Hybrid Sensor, and calibrates itself with a motor-driven internal weight. The swing-arm display, stainless construction, and IP65 rating suit benches and floor stands in wet or dusty areas.
Key Features
- 21 kg × 0.1 g (1 g selectable) with 0.1 g repeatability and ±0.2 g linearity
- Motor-driven internal calibration: one-touch CAL and Automatic Self Calibration for temperature changes
- Double-leveraged SHS sensor, about 1.5-second stabilization (FAST)
- IP65 / NEMA 4 dust and water protection, stainless steel construction
- 384 × 344 mm (15.1 × 13.5 in) pan
- Swing-arm VFD display with capacity indicator
- Comparator (HI/OK/LO), percent, counting with ACAI, animal weighing

Calibration for the GP-20K and GX-22001L
Already own an A&D GP-20K? 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-22001L? 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-20K 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-20K discontinued?
Yes. The GX-22001L Apollo is the current A&D balance with the same 0.1 g readability at about the same capacity.
What replaced the A&D GP-20K?
The A&D GX-22001L, with 0.1 g readability and internal calibration in a 22 kg capacity. Call us at (832) 290-3120 and we’ll help you pick the right model.
Does the GP-20K have internal calibration?
Yes. A&D specifies motor-driven internal calibration with Automatic Self Calibration.
Can MNM Scales calibrate my GP-20K?
Yes. Choose in-house calibration with a certificate, using NIST-tested weights, for $250, or NIST calibration with a NIST-traceable certificate for $595.
