Lab Hours of Operation

  • Important Notice: Please be advised that as of October 14th, 2016, the Weights and Measures Metrology Laboratory (“Lab”) will be unable to accept test equipment for calibration and certification. As you are aware, Tim Osmer accepted another position within the Division this past spring. Richard Cote, part-time Metrologist, will be ending his employment as of October 14th, 2016. We have been unable to fill the vacant Metrologist position with a qualified person and until we do, the Lab will need to close until further notice.

    We apologize for any inconvenience this may cause and suggest that you contact one of the other state labs to secure a date to drop off your equipment for its annual certification.Rest assured that we hope to find and hire a qualified candidate for the metrologist position in the near future, and we hope this temporary closure will not be for too long.

    As soon as the Lab is able to provide services, we will notify you.

  • Drop-off Hours: 8:00 a.m. – 3:30 p.m. Monday through Friday
  • Laboratory Telephone: (603) 271-0894
