- NIST calibration with a NIST-traceable certificate: $395. Full calibration documented on a NIST-traceable certificate, for shops, stores, and inspections 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.
