• Where can I find the serial number on my Met One instrument?

  The serial number is typically located on a silver product label on the unit and is also printed on the calibration certificate. It generally consists of a letter followed by a unique five-digit number.

• Is it safe to open the instrument cover for maintenance?

  No. Many Met One instruments (such as particle counters) are Class I laser products. Opening the cover may expose you to hazardous laser radiation. There are often no user-serviceable parts inside.

• How do I obtain a Return Authorization (RA) number?

  To return equipment for service or calibration, you must contact Met One Instruments technical service to obtain a Return Authorization (RA) number prior to shipping the unit back to the factory.

• How often should radiation shields be cleaned?

  Radiation shields should be inspected and cleaned at least annually, or more frequently in harsh environments, to remove dirt and debris that could affect airflow and reflectivity.
