WQ-330 Series: The Rugged Water Quality Monitoring

May 1, 2026

WQ-330 Series: Triple Channel Digital Water Quality Meter

Irish weather is unpredictable, but your water quality data shouldn’t be.

For technicians managing wastewater treatment or drinking water networks, the WQ-330 Series is a game-changer.

Designed for the toughest field conditions, these multi-parameter meters offer a rugged, IP67 waterproof build that handles the Atlantic rain as well as it handles a laboratory desk.

A Durable Multi-Parameter Water Testing In The Field

With the ability to swap sensors for pH, EC, and DO seamlessly, the WQ-330 ensures that reporting to the EPA is backed by digital stability. No more manual calibration headaches—just fast, repeatable results that keep our public water systems safe and compliant.

Beyond its physical durability, the WQ-330 features a large, backlit digital display that is legible in low-light wastewater environments. This ensures that technicians can take accurate readings at any time of day, reducing the margin for human error during critical inspections.

The integration of smart sensor technology means the meter automatically recognizes which sensor is attached and recalls its calibration data. This “plug-and-play” functionality is essential for high-pressure environments where time is of the essence and equipment reliability is non-negotiable.
