OWM's National Legal Metrology Program (NLMP) is hosting a new series of Weights and Measures Information Hours. Each "Info Hour" session (one-hour duration) will feature relevant weights and measures topics while providing a forum for technical discussions and Q&A. This informal meeting format will also allow networking with NLMP staff and other subject matter experts (SMEs) by sharing common knowledge, unique experiences, and other insights. All are welcome to attend, learn, and exchange information!

The NLMP Weights and Measures Info Hours will be held approximately once a month. There is no registration fee or prerequisites required for attendance. Recordings of each event will be uploaded to both this page and the e-Learning Resources page. Please check back regularly for updates.
