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.
