Calibration Options from MNM Scales
Get your EJ-6100 calibrated and ready to use on day one. Add either option to your order, and our TDA-registered technicians calibrate it in-house before it ships:
- In-house calibration with certificate, using NIST-tested weights: $195. We calibrate and verify your EJ-6100 with NIST-tested weights and include a calibration certificate, so it arrives set up and accurate. Add $195 calibration to cart
- NIST calibration with a NIST-traceable certificate: $495. Full calibration documented on a NIST-traceable certificate, for schools, labs, and audits that need a paper trail. Add $495 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.
