CTT 100S

Product Description

CTT-100S Toroidal Conductivity / TDS Transmitter is a robust, two-wire loop-powered transmitter designed for accurate online conductivity and TDS measurement in demanding industrial applications. It accepts input from a toroidal conductivity electrode, making it ideal for fluids with high conductivity, coating, or fouling tendencies. The measured conductivity signal is transmitted as a stable 4–20 mA output with optional HART communication, ensuring seamless integration with control systems. A backlit LCD display provides clear real-time indication, while auto or manual temperature compensation using RTD PT-100 / PT-1000 improves measurement accuracy. With high accuracy of ±0.25% of full scale, fast response time, and low power consumption, CTT-100S delivers reliable performance. Housed in weatherproof IP65/IP67 or CMRI IIA/IIB flameproof enclosures, it is well suited for chemical processing, wastewater treatment, pulp & paper, and industrial process monitoring applications.
