Repair & Service

Expert repair for all major water quality monitoring equipment brands

Our Commitment

Going Beyond Just Repair

At HydroTech, we go beyond repairing the equipment. We upgrade, retrofit, and redesign equipment and parts if needed.

HydroTech was the first to provide a free estimate and a service contract that covers accidental breakage of units — and we still do.

With 30 years of experience in the water quality monitoring equipment field, we are trusted by more than 2,000 customers worldwide — including the USGS, US Bureau of Reclamation, US EPA, US Fish & Wildlife Service, and US Army Corps of Engineers.

We also honor manufacturer warranties so you do not have to worry about it.
