As part of the certified lake monitoring process, Lake Stewards of Maine (LSM) and the Maine Department on Environmental Protection (DEP), ensure the calibration and functionality of all volunteer water quality dissolved oxygen meters. This service is FREE, the only cost potentially arising from replacement of components in a meter – we will consult with you about this.
The central step in this process is MeterFest. MeterFest is a one or two day event where LSM and DEP staff will check the condition and operation of dissolved oxygen meters that have been sent / brought in at no charge. We conduct routine maintenance to the extent possible and we test the equipment in the lab and evaluate the performance of the meter. This service generally costs hundreds of dollars when provided by a manufacturer or affiliated technician.
Because this is a time-consuming task, we ask that you attempt to get your meter to us for MeterFest and that you review and follow all of the steps in the MeterFest Checklist.
MeterFest date is April 12, 2023. All meters must arrive prior to April 12th.
If you miss MeterFest, we can still check your meter, but it will not be as quick a turn-around. Contact us to inquire if you missed MeterFest.
