Water Quality MeterFest and Meter Maintenance

What is MeterFest?

As part of the certified lake monitoring process, Lake Stewards of Maine (LSM) and the Maine Department of Environmental Protection (DEP) provide free calibration and maintenance for volunteer water quality dissolved oxygen meters. The only potential cost is for replacement components, which we will discuss with you beforehand.

At MeterFest, LSM and DEP staff:

• ✅ Inspect and test dissolved oxygen meters at no charge
• ✅ Perform routine maintenance (when possible)
• ✅ Evaluate equipment performance in a controlled lab setting

This service typically costs hundreds of dollars when done by a manufacturer or technician—but it’s free for you!

Drop-Off & Shipping Options

This year, we offer shipping to Augusta DEP or drop-off at five locations:

• 📍 Auburn – LSM Office
• 📍 Augusta – DEP Office
• 📍 Bangor – Penobscot County Soil & Water Conservation District (SWCD)

Since this process takes time, we ask that you submit your meter for MeterFest and follow all steps in the MeterFest Checklist.
