Calibration for the GX-20K and GX-22001M
Already own an A&D GX-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-22001M? Add calibration to that order and it ships calibrated:
- In-house calibration with certificate, using NIST-tested weights: $250. We calibrate and verify your GX-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.
