Calibration Options from MNM Scales

Get your HT-300 calibrated and ready to use on day one. Add either option to your order, and our TDA-certified technicians calibrate it in-house before it ships:

• In-house calibration with certificate, using NIST-tested weights: $95. We calibrate and verify your HT-300 with NIST-tested weights and include a calibration certificate, so it arrives set up and accurate. Add $95 calibration to cart
• NIST calibration with a NIST-traceable certificate: $395. Full calibration documented on a NIST-traceable certificate, for schools and shops 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.

Frequently Asked Questions

How long do the batteries last?

Up to 500 hours on 4 AA batteries, which are included.

Can I weigh with the scale in its case?

Yes. The HT-300 works inside its hard case, which also protects it in a backpack or toolbox.

Is the HT-300 good for jewelry?

Yes, for weighing pieces and findings in grams and troy ounces. For buying or selling precious metals by weight, choose an NTEP Class II balance such as the A&D FX-300iN.

Can MNM Scales calibrate the HT-300 before it ships?

Yes. Choose in-house calibration with a certificate, using NIST-tested weights, for $95, or NIST calibration with a NIST-traceable certificate for $395.
