Originally founded as a spin-off of Johnson & Johnson, Sentron brings decades of expertise in sensor technology to Millar. This acquisition has enhanced our capabilities and offerings, allowing us to provide more innovative solutions for your sensing needs.
Backed by Millar’s legacy of precision, our electrical conductivity (EC) sensors deliver accurate, real-time data that make devices smarter.
Integrate EC sensing technology into your agricultural devices and systems to enable real-time insights into soil salinity and nutrient levels. Our EC sensors support smarter agriculture by helping device developers build better irrigation, fertilization and yield optimization tools.
Our EC Sensors enable continuous conductivity monitoring for quality assurance and process control. Reliable electrical conductivity measurements help optimize technology that reduces waste, ensures compliance, and supports system-wide efficiency in demanding industrial environments.
Dependable EC sensing is crucial for environmental monitoring systems. Our miniaturized, high-fidelity EC sensors provide real-time water quality data that supports ecosystem protection and smarter resource management.
Electrical conductivity (EC) is a measure of a liquid’s ability to carry an electrical charge, which directly relates to the concentration of dissolved ions. Sentron EC sensors are manufactured in our own foundry and are often paired with pH sensing to deliver a more complete picture of liquid chemistry. This combination helps maintain optimal conditions, improve product quality, and detect early signs of contamination or imbalance.
Sentron’s EC sensors are engineered and fabricated in our own semiconductor foundry, ensuring full control over quality, consistency and performance. Built with robust, IP67-rated materials, they’re ready for demanding applications.
Our EC sensing elements are versatile and durable, allowing for seamless integration into a variety of device form factors and use cases without compromising accuracy.
All of our EC sensors include Automatic Temperature Compensation (ATC) and a broad measurement range (50–111,800 µS/cm), delivering high accuracy: within 1% in the 50–12,880 µS/cm range.
Our EC sensors are glass-free and rugged enough for integration into outdoor, lab-based, greenhouse or industrial devices.
