Precision at Your Fingertips for Everyday Water Monitoring
Whether you're managing a hydroponic system, fine-tuning an aquarium, or checking the quality of irrigation water, precision matters. Even small shifts in water conductivity can significantly impact plant health, aquatic life, or process outcomes. That’s where the Milwaukee C65 comes in – your trusted tool for fast, accurate EC and temperature measurements in low-range environments.
Designed for professionals and serious hobbyists alike, the C65 delivers reliable results right where you need them: in the greenhouse, the classroom, the lab, or in the field. Its low-range EC measurement (0–1999 µS/cm) makes it ideal for freshwater applications, hydroponic nutrient solutions, and irrigation water testing, while the built-in Automatic Temperature Compensation (ATC) ensures accuracy across changing conditions. With a waterproof body and replaceable electrode, this portable meter is built for repeatable performance in real-world conditions.
From agriculture to aquaculture, education to industrial water systems, the C65 offers reliable, user-friendly conductivity testing – backed by Milwaukee’s commitment to quality.
